TIPS OFF COMPUTER
The ‘Tips and Tricks’ is one of the most important part of computer learning,
since it helps in exploring the hidden secrets of Windows, thus it makes
working on computer simple and convenient. These are a few questions
related to computer and answers thereof that one may like to go through and it
may help the users in solving their problems. PC imperfections in Windows XP
number as many as its wonderful features.
1. Trouble browsing ebook and MS Office 2007 files
I downloaded some ebooks through the Internet. I’m unable to open
some with the following extensions: .docx, .djvu, .chm.
If I open a problematic .chm file, it shows a blank display, but I‘m
able to open other chm files. Please suggest a solution.
In Office 2007, Microsoft has added the new Office Open XML Formats in Word
2007, Excel 2007 and PowerPoint 2007 that includes extensions such as .docx,.
xlsx, .pptx, etc.
Office XML Formats use ZIP compression technology to store documents that
reduce the size of Word, Excel, and PowerPoint files and improve data recovery in
corrupted files. To make use of Office 2007 files such as .docx, .xlsx, .pptx etc
files, a free downloadable “Office compatibility pack” is available from
Microsoft. File Name - (Fileformatconverters.exe of - Size 27.5 MB)
The office compatibility pack supports the previous versions of Microsoft Office 2000,
XP, 2003 and can be downloaded from http://support.microsoft.com/kb/923505.
The DjVu file format allows the distribution, on the Internet, of very high-resolution
images of scanned documents, digital documents, and photographs.
DjVu achieves compression ratios that are about five-ten times better than existing
methods, such as JPEG and GIF for colour documents, and three-eight times than
TIFF for black and white documents.
Scanned pages at 300 DPI in full colour can be compressed down to 30 to 100 KB
files from 25 MB. Black-and-white pages at 300 DPI typically occupy 5 KB to 30 KB
when compressed.
To view a .djvu file, you can download Djvu Browser Plug-ins or Djvu Viewers
from the Internet. WinDjView-0.5.exe (Size 508KB) is one such free Djvu Viewer
windows application that can be downloaded from
http://sourceforge.net/project/showfiles.php?group_id=114927.
Please note, there is no need to install it, you will have to only double-click
WinDjView-0.5.exe.
The DjVu browser plug-in is also available for standard Web browsers on various
platforms at this URL: http://djvu.org/resources/
The .chm file format is a compiled HTML Help file. After you install security update
896358 or Microsoft Windows Server 2003 Service Pack 1 (SP1), you may

experience this problem of not being able to open HTML Help files from Internet
Explorer. To resolve it, please follow any one of these two simple workarounds.
The first one is, double-click the .chm file. This will bring up an “Open File – Security
Warning” dialog box. Click to clear the “Always ask before opening this file” check
box and click open.
Another method is, right-click the chm file, and then click properties.
Click the “Unblock” button and click ok. Now double-click the .chm file to open the
file.
2. Why system hangs suddenly
In the problem of frequent hanging of system. There are two other
causes of frequent computer hang-ups.
1. Presence of bad sectors in the hard disk: Bad sectors are unreadable or unusable
areas of the hard disk that are mainly created due to mechanical errors in the hard
disk. When such an area comes in contact with the read/write head of the hard
disk while reading data, unfortunately the damage suffered spreads over other
good sectors. These bad sectors are physical damages and so the only option is
replacing the entire hard disk.
The best thing is to salvage as much data as possible and bail out of such a hard
disk. However, every partition can be tested for whether it is really a victim of bad
sectors through the following methods:
Right-click any partition and choose properties. Under the Tools tab, run Error
Checking. Make sure you check ‘Scan for and attempt recovery of bad sectors
option’ while doing so.
Though actual recovery of the damaged sectors is not possible, usage of the
remaining undamaged part of hard disk is possible through efficient planning of
partitions, leaving the damaged sectors as deleted partitions without any filesystem.
2. The system might get heated due to an improper cooling system – by way of an
inefficient exhaust system and the failure of processor fans or SMPS fan.
Please make sure the fans are in working condition and the processor doesn’t get
heated up when the system has been working for a while. Excessive heat is also a
reason for turning the machine into some abnormal system, and it finally leads to
hang-ups and freezes.
Awareness of these two scenarios will help computer users tackle the problem
of system hanging better.
3. System trouble
I am using Windows XP operating system with 128 MB RAM and a
P4 processor. My system works fine for an hour and then hangs
suddenly. I am forced to restart it. I have reinstalled the operating
Computer related Tips & Tricks
Page 2 of 26
system and changed the RAM too, but the problem persists. Please
suggest a solution.
There can be many reasons for the computer hanging after working for some time. It
can be due to a faulty RAM, virus infection, defective SMPS, etc.
Some types of faults in the RAM are not detected at the time of booting. The
computer hangs only when that area of RAM is used for running the applications.
Such faults can be detected by running the memory diagnostics. One such memory
testing utility is mtinst.exe from the URL http://oca.microsoft.com/en/mtinst.exe.
One more tool is the memtest86 (Size 50 KB), which can be downloaded from the
URL, http://www.snapfiles.com/reviews/Memtest86/memtest86.html
The recommended memory for Windows XP OS is 128 MB or higher. If you are
using memory-hungry applications, you will have to increase the RAM. Some
applications hang if the virtual memory is low.
You can increase virtual memory by following this procedure. Please right-click ‘My
Computer’ and click ‘Properties’. In the ‘System Properties’ window, go to the
‘Advanced’ tab. Click the ‘Settings’ button in the performance box. In the
‘Performance Options’ window, click the ‘Advanced’ tab. Click the change button to
change the virtual memory. It is recommended to set the virtual memory size to
double the size of physical RAM installed.
Please make sure your operating system (OS) is patched and updated with the latest
windows updates and that the anti-virus software has the latest virus definitions
loaded. The computer may hang due to virus attack.
The SMPS may not be able to supply power to the computer for a prolonged
duration. In this case, try changing the SMPS.
You can investigate the reason for the computer hanging by looking up the
Event Viewer logs. These logs can be opened from Start -> Settings -> Control
Panel -> Administrative Tools -> Event Viewer.
In the event viewer, please look up the Application Log for any application-related
messages and System Log for system-related messages.
If you plan to reinstall the OS, back up the necessary data and format the OS
partition fully and install the OS. At times, reinstalling the OS without formatting may
not solve the problem. It is always advisable to do a full format of the OS partition.
Boot the computer in safe mode and check if it is stable for a prolonged
duration in safe mode.
If the computer hangs in safe mode too, there are possibilities of memory fault or an
SMPS problem. If the computer is stable in safe mode, then the problem could be in
any one of the drivers. In safe mode, the computer boots with the windows default
drivers.

4. System Restore in Windows XP
Recently I restored my computer to an earlier date as I felt that
some programmes installed were causing problems. After this
restoration, the system is functioning well. However, since then, I
have been wondering what has happened to several programs, of
15/20 MB size, installed prior to the Date of Restoration. These
programs are not listed in All Programs. What has happened to
them? Are these stored in some location of the computer which is
not accessible to me? Please suggest a solution.
Once you install Windows XP, if your system has at least 200 MB free space,
System Restore is automatically turned on, with monitoring status for all drives.
System Restore monitors only system files and registry information, it will not monitor
user files. When you revert to a restore point, however, you lose all changes
since that point, except for changes to files in the My Documents, favorites
folder, and Application files types, for example doc, xls, mdb, pdf, dbx
(Outlook Express), pst (Outlook), etc. In other words, System Restore does not
change your documents.
If you use System Restore and don't like the new system state, you can undo the
process and restore the machine to the system state it had before you ran System
Restore.
Alternatively, you can run System Restore to change the system state to a
different restore point.
With specific reference to your query, System Restore does not completely uninstall
any program if restoring to a point prior to the program installation. Programs
installed in between the dates of Restoration will become orphan programs and they
may not work because they may not have the required registry information. The
installed application folders may exist in the "Program Files" folder but the program's
DLLs, EXEs, INIs, etc, will not be there. Also, these applications will not be listed in
Start - All Programs.
If you need that application or program, you will need to reinstall that application. If
you do not need that application, then please uninstall the program through "Control
Panel" - "Add or Remove Programs". If it is not listed in Add or Remove Programs,
simply delete the program folder, which exists in C:\Program Files folder. Please
substitute the drive letter accordingly instead of C.
If you enable system restore, restore points are saved in the location c:\ system
volume information\restoreGUID.
GUID is a unique 32-character alphanumeric identifier. Each restore point's files are
saved in a folder named RPXX (such as RP01, RP02, etc,) where XX is a two digit
number corresponding to the restore point.
In Windows XP, System Restore allocates 12 per cent of your hard disk space
on each drive and you, with admin privileges, can change this setting.
By default, System Restore deletes restore points after 90 days. Normally,
System Restore creates a restore point every 24 hours if you leave your computer
on.

5. Language and Keyboard Layout
For the past one month, my computer keyboard has been giving
trouble. If I type @ symbol (shift 2) it shows " (double quotes)
symbol. This is happening with Internet Explorer.
The second problem is, if I right-click My network places and select
search, if I type \\hrd1, it appears as ##hrd1. Both the @ symbol and
\\ symbol work fine in Word 2003. This trouble arises only with
Internet Explorer and My Network Places. Is this a keyboard
problem or are any system files corrupted? Please suggest a
solution.
More than one language for text input is installed in your computer.
Generally, the default language installed in computers is English (American) and
the keyboard layout is US. It is possible to install more than one language and
select the required keyboard layout for each language. Some of the keys change for
each language and layout combination
The input language is language used to insert text. If more than one language is
installed in the computer, then all the languages are loaded into memory when the
computer is started. One language is made the default input language.
When multiple languages are installed, an icon is displayed in the task bar. When
you click this icon, it lists the languages installed and the currently selected language
is indicated with a tick mark. The language bar can be displayed on the desktop or
taskbar. If you want to change to another language, please click the language bar
and select the required one. The key sequence, Shift and Alt, will switch between the
languages.
The procedure to install additional language and layout is follows. In Windows XP,
click start, click settings. Open “Control Panel”. If you are in “category view” switch to
“classic view”. Open “Regional and Language Options”. Click the languages tab. In
the “Text services and input languages box”, click “Details” button. Under the
settings tab, in the “Default input language” box, please select the language. Only
the installed language is listed in this drop-down box. A new language can be added
by clicking the Add button in the “Installed services” box. The display of the language
bar is as per the selection available in “Regional and Language Options”, Details,
“Language Bar” button in the Preferences box. The keyboard shortcut key to toggle
between the languages can be set by clicking the “Key Settings” button in the same
Preferences box.
In Vista, please Open the control panel. Open the “Regional and Language
options”. There, go to the “Keyboards and Languages” tab. Click “Change
Keyboards” button. Click “Add” button in Installed services. In the “Add input
language” dialog box, select the keyboard layout and add from the list below.
To set a keyboard layout as default, select the required one from the dropdown list
under “default input language” on general tab and Click ok to save changes.
Computer related Tips & Tricks
Page 5 of 26
In Word 2003, there is an option to select the language. In Tools menu, Language,
Set Language will display the list of languages and also the default language. To
solve your keyboard problem, you can make English (US) the default language and
US as the keyboard layout. Or you can also remove the other language
6. Making Excel as database
I would like some guidance regarding use of Excel. I have three
Excel sheets, two with my inputs (tables) and the third sheet is my
database. All three sheets have the same number of columns. If I
change anything in either of the two sheets, it ought to get reflected
in the third sheet too, that is in my database. How can I go about it?
It is possible to update changes to the excel database, by using Excel macros
or with the help of any front-end applications.
Before we go further, let us first take a look at excel as database. The basic format
for storing data in an Excel database is a table. In a table, data is entered in rows.
Each row is known as a record. After the creation of table, Excel's data tools can be
used to search, sort and filter records in the database to get the required information.
Creating a list from the data in a table is the easiest method of using the data tools.
For creating an Excel DB, the first step you need to follow is to enter the data with no
blank rows. A record can contain data about only one specific item. A record must
also contain all the data in the database about that item, not more than one row.
Column headings are called field names and are used to ensure that the data for
each record is entered in the same sequence and is consistent. After the data has
been entered into the table, it can be converted to a list. To do that, please select
any one cell in the table. Then Choose Data> List > Create List from the menu to
open the Create List dialog box. The dialog box displays the range of cells needed to
be included in the list.
If we create the table correctly, Excel selects the correct range of fields. Click ok if
the range is correct. If the list is incorrect, please click the return button of list box for
getting back to worksheet; it will appear as a small box and the current range of cells
will be surrounded by marching ants. You will need to select the correct range of
cells by dragging the mouse and clicking the button on list box for return back to the
normal size and click OK for finishing.
After completion, the list will have a dark border around it and each field name will
have down arrows, which will open drop-down menus when clicked. Options such as
sorting the DB with field names and searching for records from DB are possible with
dropdown menus. Additional data can also be added using blank row containing an
asterisk at the bottom of the list.
Merging or combining two excel tables into one database excel file can be based on
a common column of data from each file. The two tables can be located in the same
Excel file or two different Excel files.
The concept behind the issue is loop into the worksheets, based on a common field
for insert and update the data.
For example, name a variable `sh' and loop the worksheets. For each `sh' in this
Worksheet. If sh(name) is not equal to destination.name, then insert into last row
(destination name). Likewise, for updating any changes in the worksheets to reflect it
on destination (Database), you will need to loop through the worksheets with
Computer related Tips & Tricks
Page 6 of 26
variable, find out any changes, and update it. This can be done with the help of an
excel macro based on this concept.
By Using Visual Basic.Net 2005 - VSTO (Visual Studio Tools for Office), this can be
achieved with WorkBook.MergeFile method.
You will need to import Microsoft.Office. Tools. Excel for this.
Here is a sample coding: Dim objFirst As Worksheet = New Worksheet
Dim obj,objFirst,objSecond,ObjThird As New Workbook
objFirst = New WorkBook.Open(firtFile)
objSecond
=
New
WorkBook.Open
WorkBook.Open(thirdFile)
(secondFile)
objThird
=
New
objThird.Merge(objFirst, objSecond)
Close and dispose all the variables.
There are various tools and add-ins for merging data sheets into a single Excel
workbook.
7. Saving password setting
I registered my Web domain, and have subscribed to business mail
via VSNL. Although I have configured my two mail accounts, they
show errors at times. (I still am able to send and receive mail).
My Incoming server is: pop.sme.vsnl.com My outgoing server is:
smtp2.sme.vsnl.com My Internet connection is from BSNL. Every
time I open Outlook, there's a pop up that says, `Enter network
password,' with space for server name, user name and password.
Despite my filling the above spaces, the pop-up reappears. The
customer support executives are unable to help. Please suggest a
solution.
From your query I assume two e-mail accounts (VSNL) have been configured in
Outlook. You have mentioned that if you press send/receive button, the system
some times shows errors. This may happen due to the pop/smtp server being busy
at that moment.
So you could try after a minute or two. Regarding the pop-up that prompts you to
enter the network password repeatedly, you say that you are still able to send and
receive mail. This problem may be due to one of your SMTP mail accounts'
password being incorrect. To address this issue, you will first have to configure your
two e-mail accounts in different profiles, please do not keep them in a single profile.
This way, you can test both individually.
Please send a test mail to your configured email account and verify whether you
receive mail. While configuring the mail account, in the "Enter Network Password"
dialog box, do not enable the "Remember Password" option. Once you confirm you
receive mail, enable (tick) this "Remember Password" option. So, in future, it will not
prompt for Server password when you open Outlook.
If you do not get the test mail, and get "Enter Network Password" pop-up repeatedly,
then please do the following. First temporarily disable your windows firewall
(Personal firewall) and the Email Auto- Protect Settings of your Anti-virus product.

Now send a test mail and check whether this solves your problem. If it still exists,
please change your ISP server password and check whether this helps.
To change e-mail account password, please refer http://mybusiness.vsnl.in/
faq_businessmail.aspx#16
If still unsuccessful, please start Outlook in safe mode and repeat the test. To open
in safe mode, follow these steps: For Windows 2000/XP/2003, click Start - Run. In
the open box, type "outlook.exe /safe" (without quotes) and click ok. For Windows
Vista, type "outlook.exe /safe" in the Start Search box and press Enter.
In safe mode Outlook runs without any other non-Microsoft service. If Outlook runs
correctly in safe mode, chances are that the issue is caused by a third-party service
that is working with Outlook (for example, add-ins, Anti-virus software, or firewalls).
8. Windows boot error
I have a problem with my laptop and would like to know if you can
assist me in finding a resolution. I formatted and installed Windows
XP on my laptop and updated all the drivers from the Web site. But
whenever I install Service pack 2, Windows does not restart and
instead displays an error message. If I go into safe mode and
uninstall Service pack 2, Windows starts okay. Other than Windows
XP the only software I have installed is Norton Internet Security and
that works fine. The error message I get is given below:
“A problem has been detected and Windows has been shut down to prevent damage
to your computer.
“BAD_POOL_HEADER
“If this is the first time you have seen this stop error screen, restart the computer. If
this screen appears again, follow these steps: “Check to make sure any new
hardware or software is properly installed. If this is a new installation ask you
hardware or software manufacturer for any windows updates you might need.
“If the problem continues, disable or remove any newly installed hardware or
software. Disable BIOS memory options such as caching or shadowing. If you need
to use safe mode to remove or disable components restart your computer press…
“Technical Information:

dump of physical memory
“Dumping physical memory to disk”
The error messages are due to a faulty driver or service. If the device is an add-on
card you can try removing it and booting the computer.
If the computer still cannot boot, then you can disable the driver or service either
using safe mode or from the “Recovery console”.
Computer related Tips & Tricks
Page 8 of 26
To enter into safe mode, please follow the steps: Restart the computer. While
booting, tap F8 function key until you get the “Windows Advanced Options Menu”
and select Safe Mode. After logging in to the system you may disable the
problematic driver or service.
To go to the recovery console, boot the computer from the XP Operating System
CD. At the “welcome to set up” screen, press F10 or press R to repair.
This will list the Windows Installations found on the disk. Select the appropriate one.
There will be a prompt for the administrator account password.
After logging in, use the “listsvc” command to list the services and drivers on the
computer. Note the name of the driver or service to be disabled.
Disable the service or driver using the “disable servicename” command.
This command will display the old start_type before disabling the service. Find out if
the service has to be enabled again from the recovery console. After eliminating the
service or driver that causes this error a newer, error-free version can be installed.
9. Retrieving important files
I use a system with these specifications: 3.06Ghz Intel, 80GB HDD,
Intel D101ggc motherboard and Windows XP SP2.
Recently, the system automatically rebooted itself and displayed
options such as `safe mode, safe mode with command prompt,
Networking' as it shut down abruptly. I tried out all the options one
by one. System boots up to the windows logo and the sliding blue
bar boot screen, then it automatically restarts, only to repeat the
above-mentioned steps. I tried the following:
Reinstalled windows in the G drive. It got successfully installed.
When I went back to c:\documents and settings\user folder to
retrieve essential data, it displayed the `Access denied' message. I
tried it through command prompt too only to be greeted with the
same message. I tried repairing it using windows installation CD,
but was not successful.
When I tried to scan the c:\docs and settings\user folder using
Norton anti virus (installed a new in G drive), it displayed the name
of all the files and folders. I hope this indicates that all the files still
exist. The files are important and I need to retrieve them at the
earliest. Data is around 1GB. Please suggest a solution.
The user folder in "Documents and Settings" is set with full permission for the
corresponding user. One user will not be able to access another's folder in
"Documents and Settings". If the operating system crashes and is reinstalled
in a different drive, then the user logged in from the new installed OS will not
be able to access the previous Documents and Settings user folder. The old
Computer related Tips & Tricks
Page 9 of 26
Documents and Setting user folder has to be given permission for the required
user.
The administrator has to take ownership of the user folder and its contents. After
this, the necessary permission for the folder has to be set. After logging in as an
administrative user, to take ownership of the user folder, please right-click the user
folder in C:\Documents and Settings and click Properties; Click the Security tab;
Click Advanced and click Owner tab. In the name list, the logged in username and
the Administrator group will be displayed. Select any one and select Replace owner
on sub containers and objects. Click Ok and then click Yes for the message. Click
Ok to close the Properties window.
This will take ownership of the folder and its contents and set the full control
permission for the folder. After this, you can copy the files and folders in the
Documents and Settings\User folder. There can be some folders where even if
you change the permissions to the folder, it is not possible to access the
contents or not possible to change the permissions. The folder might be
inheriting permission from its parent folders.
To remove the inheritance from the parent folder, please right-click the folder
and click properties. Click the security tab. Click advanced. In the permissions
tab, the check box "inherit from parent the permission entries that apply to
child objects. Include these with entries explicitly defined here" will be
selected by default. Remove the check box. During removal, the check box will
prompt you to select one of the options: To copy the permission entries those
were previously applied from the parent. To remove the permission entries those
were previously applied from the parent and keep only those permissions explicitly
defined here.
10. Vista UAC dialog screen
I bought a new computer last month with Windows Vista Ultimate
operating system loaded. It is very difficult to work in Vista and I
lose patience because for most of the tasks, such as installing
acrobat reader, to run disk defragmentation, to change firewall
settings, etc, a dialog box appears and asks for administrator's
password. Every time, I need to type the administrator's password
to continue. Is there any way to tackle this? Please suggest a
solution.
You may create two types of user accounts in Windows Vista, namely Administrator
and standard user. Whenever you perform a task that requires administrator
privileges, say, adding or removing software, changing user accounts, and even
modifying the Windows Vista configuration, etc, you will get a "User Account
Control (UAC)" dialog box with warning prompt. This Dialog box may vary
depending on the type of user (Administrator or Standard user) that you have logged
in as.
Normally, if you login as a user with administrator privileges, you will be asked to
confirm that you want to continue with that action. So just click the "Continue" button
to gain the elevated rights needed to complete the admin task. If you login as a
standard user, then you will be asked to provide a password for an administrator
account. In your case, you appear to have logged in as a standard user, so you are
Computer related Tips & Tricks
Page 10 of 26
required, every time, to provide password to gain the elevated rights to complete the
admin task.
If you would like to have UAC enabled and avoid typing password every time, then
you can go about this in two ways. One is login as a user with administrator privilege,
that is add administrator privilege to your vinoth account. So you will get UAC popsup with continue warning message. Now click the "Continue" button to gain the
elevated rights.
The second way is to login as a user account with standard user but set the
administrator account without a password (blank password). In this case, UAC will
prompt for password and you will have to just click the ok button to continue to gain
the elevated rights.
If you would like to avoid even the UAC "Continue" pop-up screen (disable UAC),
this is how you do it.
You can disable this by using "Elevate without prompting" local policy. First click start
- type "secpol.msc" in the "start search" box. This will bring up the Local Security
Policy screen. Expand (double click) the "Local Polices" Folder and then "Security
options". On the right pane, please scroll down to the bottom and double-click the
policy "User Account Control: Behaviour of the Elevation Prompt for Administrators in
Admin Approval Mode". In the drop-down list, select the "Elevate without prompting"
option and click ok.
Please note that disabling UAC is not recommended because it is amongst the
good security enhancement features of Vista.
Restricted access
How do I give login access to an individual, for a particular time
during the day, in Windows 2003?
It is possible to control user access for a particular time of the day. If the machine is
part of Windows domain, you will have to make the settings in the domain, not the
workstation. In the domain controller, you will need to create a group policy for
setting the login access restriction. You can also have the user logged out when the
logon time expires.
To set a logon time restriction for an individual user in the domain, first logon
to your domain controller with admin rights, then go to Start - "Control Panel" "Administrative Tools" - "Active Directory Users and Computers". In the left
column, please expand the domain where you want to create a group policy.
Click on the Users container. On the right column, right-click on the user you
want to modify and select Properties. Select the Account tab. Click on the
"Logon Hours" button. Adjust the hours to either allow or deny the user the
ability to logon at that time of day.
For Automatic logoff of the user, you will need to create a new group policy or you
can modify the existing one. To create a new group policy, please Go to start Control Panel - Administrative Tools - "Active Directory Users and Computers". In the
left hand column, right-click on the domain and select Properties. Select the "Group
Policy" tab. Click the New button to create a new policy. Name your new policy on
these lines `Logoff user when time expires'. Select it and click the Edit button.
This will bring up the Group Policy editor. In the left hand column, please expand
Computer Configuration - Windows Settings - Security Settings - Local Policies Computer related Tips & Tricks
Page 11 of 26
Security Options. In the right-hand column, doubleclick on `Automatically logoff users
when logon time expires', check the box for `Define this policy setting' and set it to
Enabled. If the machine is not a part of windows domain, you can use a command
line tool "Net User" for giving access to an individual user for a particular time during
the day. For executing that command, first Logon to that machine with administrative
rights. Go to start - Run. In that type "cmd or command." The command prompt will
open. In this window, please type net user "user account" /time: "logon times"
The user account will have to be the user name you want to restrict and the logon
time will be the duration and the day (e.g.: net user "test" /time:M-F,13:00-14:00)
During this time, i.e between 13:00 and 14:00 hours, only user test has rights to
access that workstation.
11. Enabling Task Manager
Whenever I press alt+ctrl+del, the system says task manager is
disabled by administrator. Why is this happening? Please suggest
a solution.
The Task Manager in Windows allows users to start and stop programs, monitor the
performance of their computers, view and monitor all programs running on their
computers, including system services, find the executable names of programs and
change the priority of the process in which the programs run.
In windows XP, if the Welcome Screen is enabled for Logging in, then the keyboard
combination Ctrl+Alt+Del key will open the Task Manager.
The windows task manager will be enabled in all windows installation by default. The
system administrators can disable this for administrative reasons. This is done
through the registry setting or the group policy.
If the task manager has been disabled without the knowledge of the system

12. Browsing trouble
I got DataOne installed recently (HomePlan250) in the USB Port of
my PC System with UT300R2U ADSL2+. (Quick-Start Guide in the
package calls it Modem and BSNL Chart refers to it as ADSL
Router). There are five Green flicker lamps, in this order: (i). Power
(ii) DSL (iii) Internet (iv) Ethernet (v) USB. When switched on, the
first lamp glows OK. Then USB, DSL lamps start flickering, then the
Internet lamp. The DataOne icon appears in the task bar. I am able
to browse and download. No problem when I switch on and browse
between 5.00 a.m. and 5.30 a.m.or between 2.30 p.m. and 3.30. But
during the rest of the day, the power lamp is ‘On’ and the USB lamp
glows with or without flickering. The other two (DSN and Internet)
remain ‘off’. The icon that appears in the task bar status shows
“bytes received and bytes sent” but browsing is not possible.
When browsing is satisfactory and downloading is just fine for
about 45 minutes or so, sudden interruption occurs sometimes.
The USB lamp alone flickers. The middle two lamps are ‘off’ and
browsing is not possible. Switching off and then switching on
power sometime later is helpful occasionally but not always. Please
suggest a solution.
In a broadband Internet set-up, the telephone line is connected to the ADSL modem
and a connection from ADSL modem is connected to the computer. The physical
connectivity between computer and ADSL modem is either through a network cable
or through a USB cable. In case of network cable, there is a network adapter in the
computer and it is connected to the network port of the ADSL modem. For the USB
connection, the ADSL modem’s USB port is connected to the USB port of the
computer. For this, a virtual network adapter is installed in the computer. This is
done using the ADSL modem CD while configuring the ADSL modem in the
computer for the first time. The configuration of this virtual network adapter is the
same as the real network adapter. Broadband Internet functions only when the
connectivity between computer and ADSL modem and ADSL link is all right.
Computer related Tips & Tricks
Page 13 of 26
The ADSL modem CD documentation will clearly explain what the status of the LED
indicates. Generally, the Power LED shows the status of the Power to the ADSL
modem. The DSL and Internet display the ADSL Link status. The Ethernet LED
displays the status of the Ethernet connectivity to the computer. The USB LED
displays the USB connectivity to the computer. The Ethernet and USB LED blink
indicates some data traffic between the computer and the ADSL modem. Whenever
broadband Internet is not ok, please check for the physical connectivity between
computer and the ADSL modem. Check the virtual network adapter status in the
computer. Try opening the configuration page of the ADSL modem by typing
http://192.168.1.1 from the browser window. The IP address 192.168.1.1 is the
default IP address for the ADSL modem unless otherwise changed. If the page
fails to open, please check the connectivity by using the ping command.
Open a command prompt and enter the command ping 192.168.1.1 If you get a
reply, the link is ok, otherwise please check the interface status using commands
such as ipconfig -all and arp -a from command prompt
If the modem connectivity is all right but broadband Internet is not, then please
inform your Internet service provider that the ADSL link is not all right.
13. Intel original motherboard display
I have used Intel original motherboard in my PC. This information
used to get displayed in my old PC but not in my new one. Why is it
so? Please explain.
When the system boots, the BIOS start the POST (Power-on self-test) program. This
is nothing but the software routines that test the attached hardware devices (such as
RAM, hard disk, display, etc) and then the operating system boots. BIOS allows you
to change the settings of the hardware peripherals. To enter into the BIOS, while
switching on the system, you may need to tap any one of the following keys DEL, F1,
F2 etc. This BIOS access key may vary depending on the BIOS manufacturer, such
as AMI, AWARD or Dell.
Under options, you may see entries such as Silent Boot and Intel Rapid BIOS Boot.
You may enable or disable this option as per your requirement. If you enable the
"Intel Rapid BIOS Boot" option, it allows BIOS to skip certain tests while booting.
This will decrease the time needed to boot the system. Another option is called,
"Silent Boot". If you enable this, it Displays OEM (mother board) Logo instead of
POST message. If you disable this, it displays the normal POST message. In your
old PC, the "Silent Boot" option might have been enabled, thus it displayed the OEM
("Intel Original motherboard") screen instead of the normal POST message. In your
new machine, this option might be disabled hence it doesn't show the OEM Logo.
14. Identifying unknown devices
My computer is loaded with Windows XP as the operating system. I
would like to back up my system drivers. But three of my drivers
show a yellow question mark under `unknown devices.' How do I
proceed to take the back-up? Please suggest a solution.
Computer related Tips & Tricks
Page 14 of 26
Freeware tools are available on the Internet to identify unknown devices that are not
recognised by Windows. In Device Manager, you may see some entries with yellow
question mark under unknown devices.
To access these devices, you will need to install the correct drivers that are
bundled with your hardware or download the appropriate drivers from the
device manufacture's Web site. The utilities cited below provide information
about unknown hardware, such as Device vendor, OEM name, device type, etc,
and option to find driver for the selected device on the Internet.
Unknown Device Identifier 5.02: (size 843 KB). This identifies USB 1.1/2.0 Device,
IEEE 1394 Device, ISA Plug & Play Device, AGP Bus Device and PCI Device etc. It
can be downloaded from http://www.zhangduo.com/ UnknownDeviceIdentifier.exe
Unknown Devices 1.4.20 Beta (size 630 KB).
Please download from http:// www.halfdone.com/ukd/UKD_14- 20_Beta.zip
If you are still unable to find drivers, then you may take back-up of existing drivers
using Drivemax utility.
15. Power disruption
My PC’s configuration is as follows: Pentium D Processor (Dual
Core), Mercury 945 Mother board with Intel chip, 512 MB ddr2 ram
with LCD display. For this system, I am using offline UPS 2.00 K.V.
To the same UPS, another system of similar configuration is also
connected (in all, two systems are connected).
The problem I face is that when there is no power, one system gets
booted. Once power is restored, the other system boots. Why is
this happening? Please suggest a solution. The two systems work
perfectly under online 2.00 k.v UPS.
There are different types of UPS (Uninterrupted Power Supply) Offline, Line
Interactive and Online UPS. In Offline UPS, the power for the output load is given
from the input supply with some power conditioning.
When the input supply fails, the power is fed from the battery through a switch. When
again the input supply resumes, the output is given from the input disconnecting from
the battery
As long as the input supply is present, the battery will be charging. There will be a
break in output supply for a small duration, say, milliseconds, whenever the input
supply fails and is restored.
The offline UPS is highly efficient and low-cost. In Online UPS, the output is always
supplied from battery.
The battery gets charged from the input supply. Even when the input supply fails, the
output will be supplied. There is no break of output supply during power failure and
Computer related Tips & Tricks
Page 15 of 26
resumption. The online UPS is not that efficient. The output power is well conditioned
without any noise and voltage fluctuations.
Line Interactive UPS works the same way as the offline UPS except that there is no
break in the output supply whenever the input supply is cut and restored. In the Line
interactive UPS, there is a charger to charge the battery, the input supply is
converted to DC, this DC is again converted to AC for the output. When the input
supply fails, output is supplied from the battery. A small amount of energy will be
stored internally to reduce the break in the output during switching from input mains
supply to battery and also for the battery to input supply when the input supply
resumes.
Any computer will be able to withstand a break in supply for a small duration,
say 4 milliseconds. The exact duration can be found in the computer
manufacturer’s data sheet. In the Offline UPS, if the duration to switch between
mains input and battery is more than the PC withstanding duration, the computer will
boot. This is the reason for the computer booting when the input supply fails and
again when the input supply resumes.
Line Interactive UPS or Online UPS is the first choice for computers. The offline UPS
can be used in cases where the break in output for small duration is acceptable.
16. Downloading video
Is it possible to download YouTube videos to a hard disk? If so,
how do I go about it?
One cannot, normally, download the video from these sites. You are allowed to view
the video contents but not download or save it to your local hard disk. These sites
give users only give the option to share the content with friends through e-mail.
When you send these contents through e-mail, only the link is sent, not the full
contents. The video content in these sites is mostly made of adobe flash player.
Usually, when you open a streaming video file from the site, it starts buffering the
video content from the site to your local hard disk and from that buffer only will it start
playing. The location for the content from the site will be buffered to C:\Documents
and Settings\”User” (the user logged into the machine)\Local Settings\Temporary
Internet Files.
First delete all the content in this directory and start the streaming video. Once it has
buffered completely, please check whether you have any video files in temporary
Internet files directory. The video file may be with extension .avi, wmv, flv. If you
have any video file with the name with which you viewed online, just copy that file
from that directory to another directory. And check whether you are able to view the
file.
The other option for downloading or recording the online streaming video content
from the site to your local hard disk is using third party applications and tools. These
are available in the site for download, either as freeware or shareware.

select the video to play.
By right-clicking, you can get the option “download this video to real player”. Once
you select this option, it will download the video content to your local hard disk and it
will be added to your real player media library. The downloaded file will be stored in
“C:\Documents and Settings\”user” (the user logged into the machine)\My
Documents\My Videos\RealPlayer Downloads\”. You can change this path in the real
player.
Open the Real player - select Tools, in that select preference. In the preference tab
is an option called “Download & Recording.” Please select this option, here you can
specify the location to save the file.
There is another option, “Enable Web downloading and Recording.” You will need to
select this option to download and record the streaming content from the site.

18. Using MojoPac on pen drive
I have installed MojoPac on my 2 GB Transcend Pen drive. How
many cycles are provided in such drives? Is it wise to use MojoPac
on pen drive or should I move on to portable hard disk?
MojoPac is technology that enables us to carry our computer, along with data and
applications, in a portable device, instead of carrying a laptop. The portable device
can be connected to any other computer or laptop. We can access our own
computer too here. This is desktop virtualisation software.
The portable device can be USB hard disk, flash drive, iPod or even mobile phone
with storage. The size of the portable device can range from 2GB to 80GB. With this
technology, we can carry data, applications such as word, outlook, games, Instant
Messaging, Google talk and personalised settings such as desktop, themes, my
documents and my pictures.
MojoPac can be installed in Windows XP. It comes in three different forms. `MojoPac
Freedom' is a free download with minimum features and others are priced, `MojoPac
Deluxe' and `MojoPac Enterprise' with more features. More details of the features of
the application, Installation procedure and free download are available at the site
www.mojopac.com
This application needs to be installed in the computer that needs to be carried in the
portable device. Some folders, such as Program files, Documents and Settings, and
some files also get copied onto the portable device. Generally, the specification of
the pen drive mentions read and write cycles of more than one lakh operations. This
means more than one lakh read and write operations can be performed in the pen
drive.
The device will continue to work even after the specified operations. The
performance of the device may likely get reduced after the mentioned read and write
operations. When using MojoPac in pen drives, the read and write operations are
performed similar to any data access. The executables are read from pen drive and
run in the host computer. This is normal read operation.
Any changes done will be saved back to the pen drive. This is a normal write
operation. This cycle takes place each and every time you use MojoPac in a host
computer. Apart from this read and write cycle, there is no other intensive read write
operations. This should not exhaust the read write cycles mentioned in the
specifications of the device. As for the choice of using the pen drive or a USB hard
disk, it depends on one's convenience and affordability.
19. Windows Vista highlights
My system is an old one, with the following configuration: P III,
1GHZ with 256 MB RAM and 40 GB hard disk. I have loaded
Windows XP operating system with the latest service pack. Please
highlight the new features in the vista operating system.
Computer related Tips & Tricks
Page 18 of 26
The attractive features of Windows vista include Aero Glass GUI Interface, fast and
easy search, enhanced Explorer Navigation, Media Center, Tablet PC functionality,
Mobility Center and Enhanced Security and Communication. Aero Glass GUI
Interface: The windows components appear with transparent glass effect. This can
be noticed in the windows title bars, Start menu, etc. One can adjust this setting to
one’s taste. The Windows Flip and Windows Flip 3D render live thumbnail images of
the exact contents of your open windows, making it easier to identify the ones you
want. Windows Flip improves on the ALT+TAB method for flipping between windows,
while Windows Flip 3D displays all open windows in a three-dimensional view.
To get the real Aero Glass Interface effect, you need the following hardware: 1GB
RAM, and Support for DirectX 9 graphics with WDDM Driver, 128 MB of graphics
memory (minimum), Pixel Shader 2.0 in hardware, 32 bits per pixel. Vista Home
Basic version will not support AERO feature.
Vista Search and Windows Explorer: To perform a Search, just click start button and
type part of the name of any program, folder or file. Vista uses virtual folders to save
search results. There are enhancements on the Windows Explorer side too. The
address bar helps you locate all that you want to explore. Normally, one will
not notice the Menu bar. If it is required, either press Alt key or click Organise
– Layout - Menu Bar. Also the folders names such as My Documents, My
Computer, My Network Places, My Pictures, etc, appear in vista as Documents,
Computer, Network, Pictures folder.
Security: New add-ons play a major role. The enhancements include User Account
Control (UAC). Internet Explorer runs in Protected mode, with Windows Defender,
Windows Firewall, Parental Controls, BitLocker Drive Encryption, Network Access
Protection (NAP).
User Account Control improves the safety and security of your computer by
preventing potentially dangerous software from making changes to your
computer without your explicit consent. When a user (or program) attempts to
perform an admin-level task (such as install updates, install a printer, change display
settings, etc), UAC dialog prompts for an administrator’s credentials. If you are a
standard user and attempting to perform an admin-level task, then the UAC dialog
prompts for an administrator’s user name and password. For administrators, it simply
asks whether you’d like to continue with the task you’ve attempted.
Internet Explorer runs in Protected mode, which allows full access to features
and tools on the Internet but isolates IE from the rest of your computer to
protect your system.
Windows Defender is an anti-spyware product that includes Real-time protection and
Windows Firewall supports filtering for both incoming and outgoing traffic.
Using Parental Controls, you can configure Web sites your children can access,
place time restrictions, set restrictions on games, Instant Messenger, TV shows,
videos, etc, and you can view reports about their activity.
BitLocker Drive Encryption
Computer related Tips & Tricks
Page 19 of 26
If someone steals your computer’s hard disk and connects it to another machine,
then they might hack all your data. To avoid this scenario, Vista introduces a new
security feature called BitLocker Drive Encryption feature that adds machine-level
data protection. It provides encryption on the drive where the operating system
resides. It protects both boot files and OS volume using TPM technology. If you
would like to use BitLocker drive encryption, then it requires a 450 MB of separate
system partition and either TPM hardware module (version 1.2 or higher) or USB
Flash drive to store the keys. If your Mother Board is not inbuilt with TPM module,
you can still use BitLocker without a TPM Module, but no boot file validation. So you
may use USB Flash drive to store the keys instead of TPM Modules. BitLocker
feature exists only in Vista Enterprise and Ulitmate Editions.
Windows Media Center: With Media Center, you can record and watch TV (using
a TV tuner card) and even live TV. Play audio, video and burn a CD or DVD and
make your computer the centre of your entertainment world. Windows Media
Center is available only in Vista Home Premium and Vista Ultimate. Windows
Photo Gallery is for viewing, basic editing, organising, and sharing pictures
and videos.
Windows Mail: Instead of Outlook Express, Vista introduces “Windows Mail” as
default e-mail client with enhanced features. Junk e-mail and phishing filters have
been enabled. Instead of “Windows Address Book”(WAB), vista uses the new PIM
application called “Windows Contacts”. Each contact is stored as a separate .contact
file. “Windows Calendar” is a new application included in vista to store
appointments and tasks just as with Microsoft Outlook and it also allows you
to publish your calendar.
vista migration
For vista migration, there are two utilities “Windows Easy Transfer” for small
environments and “User State Migration Tools” (USMT) for large environments.
Instead of NetMeeting, vista introduces “Windows Meeting Space” application. Using
this you may collaborate with up to 10 users (only vista OS users).
20. SQL server installation
I'm using Windows XP on my system. Recently, I tried to install
SQL server 2000. While the installation was going on, my system
started hanging. After resetting the PC, I tried to install the server
again but the system displayed an error message saying some files
were already existing. So I tried to uninstall and reinstall the server
but with no success. Since the software appears to be partially
installed, I am not able to remove or add to the program. Please
suggest a solution.
If the SQL server does not install successfully, you can determine what has gone
wrong by checking two files, `Sqlstp.log' file and `Error log'. The Sqlstp.log is located
in the Windows directory. It provides detailed information on the setup and also the
errors encountered during setup. Reading this file will give you a good idea of where
the setup fails. You can also check the SQL Server error log, named `Errorlog' with
Computer related Tips & Tricks
Page 20 of 26
no file extension, located by default in the Program Files\Microsoft SQL
Server\Mssql\Log directory. This contains errors that the SQL Server encounters
during startup. When the Setup application fails, it rolls back all changes to the file
system, which includes removing any copied files and changes that were made to
the registry.
One other component you could look up is the Microsoft Data Access Components
(MDAC) setup, which is launched as part of the SQL Server 2000 setup. SQL Server
2000 setup installs MDAC 2.6. The MDAC setup creates a separate log file named
Dasetup.log; you can review this log file and make sure that there are no problems
with the MDAC setup. For more information, please refer to the following URL:
http://support.microsoft.com/kb/232060/ and http://support.microsoft.com/kb/257716
If your system hangs while you are installing the SQL server, please check whether
you have installed all the required components. While installing the SQL server,
please minimise the Setup window and other windows to see whether there are any
messages relating to File Copy or File Sharing. For uninstalling the SQL Server,
please check whether the `uninst.isu' file is present in some other folder. `uninst.isu'
is created during Setup and is found in the MSSQL directory. If you have
successfully installed the SQL server, this file will be created in the MSSQL directory.
Use the Uninstall option in the setup program. To do this : Click SQL Server
2000 Components, and then click Install Database Server. Click to select Local
Computer, and then click to select Upgrade, Remove, or
Add Components to an existing instance of SQL Server. Click to select Default
or select what you want to uninstall in the `Instance Name' drop down box, and
then click to select `Uninstall your existing installation'.
After the uninstall program is complete, you will need to clean up the files/folders
used during the process.If you cannot use this method to remove SQL Server 2000,
you can manually uninstall the SQL server. Please click on this link for more details:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;Q290991
21. Boosting system speed
I am using a laptop/system and XP OS with service pack 2 but my
system is very slow.
TuneXP 1.5 is among the best freeware and most powerful Windows XP
tweaker that supports faster shutdown, clear pagefile on shutdown, ultra-fast
boot, etc. Please read the help documentation before making changes on
TuneXP.
The best option is to increase your system memory to 512 MB or more.
Please uninstall or disable the unwanted programs from system startup.
Delete unwanted files and Defrag your hard disk. Set your pagefile size 2.5
times of your physical memory size. Next check spywares on your system.
Do Defrag on Your System Periodically
Computer related Tips & Tricks
Page 21 of 26
Another possible reason, responsible for slower system boot up is not enough
free disk space for a swapfile. Normally if you keep the size of swap file to its
maximum, then it helps in improving the overall performance of your computer,
including system bootup. Having higher RAM in is also a desirable factor. Another
way of boosting the system boot up is to regularly defrag your hard disk; this
is one of the most important functions, which has the capacity to boost your
computer’s performance manifold. Defragmentation is the process of re-arranging
the files on your hard disk, so that each file is arranged in a proper order to ensure
that the programs start faster.
Click on Start Button, Go to Programs -> Accessories -> System tools ->
Disk Defragmenter. Select the drive you want to defragment, Click Ok.
Do Fix the Size of Your Swap File
Fixing the size of the swap file cuts down on the work your system has to do and
may improve performance. Before you get started, defrag your drive. Then rightclick on My Computer and select Properties. Click the Performance tab, the
Virtual Memory button, and then the "Let me specify my own virtual memory
settings" button. In the Minimum field, enter a new amount of memory (in MB). If
your system has only 32MB of RAM, use at least 100MB of virtual memory. Enter the
value of the available space on your hard drive for the maximum (or leave it at No
Maximum). Make the amount you choose both the minimum and maximum setting.
You'll see a warning message before you can finalize the changes. Click Yes, and
Yes again, to restart your computer.
Don’t Install Games, Shareware & Avoidable Downloads
Another factor, which is important for boosting system bootup and also the overall
performance of your computer, is your attitude. Well! It may sound surprising, but
it is the truth. It is common to see computer users installing games, shareware,
fonts and lots of other drivers, which are not required at all by them. All these
programs, fonts, games, drivers that are installed on the computer do their bit
in slowing down the system boot-up. The habit of installing everything on the
computer may prove fatal. Thus avoid installing memory-based drivers,
including games, printer drivers, shareware programs, fonts etc as excess of
them is fatal for your computers performance.
Do Cleaning Your PC Periodically
Cleaning Monitor & CPU : To tackle the outside of the case and the monitor
screen, first blow off dust with the compressed air, then spray a little window cleaner
on a rag and wipe everything down. Don't spray directly on any part of the computer
because you could inadvertently spray the liquid through a vent and damage the
internal circuitry.
Cleaning Keyboard : For spills on keyboards, disassemble the unit, flip to drain, blot
if possible, blow off with compressed air, and let dry overnight. Don't expect
miracles—sugar and other residue are hard to get rid of and may permanently
damage a keyboard.
Computer related Tips & Tricks
Page 22 of 26
Cleaning Mouse : If your mouse is misbehaving, it's time to give it a bath. Remove
the round plate on the bottom of the mouse by rotating it in the direction of the
arrows. When the ball drops out, use a small screwdriver or toothpick to gently
scrape dirt off the rollers. Next, blow out the interior with compressed air, wipe dust
off the ball, and place it back inside the mouse.
Cleaning Digital Dust Bunnies : As long as you're cleaning up your hardware, you
may as well go after digital dust bunnies too. Start with your Temp folder, where
Windows stores the files it's supposed to delete (but sometimes doesn't). You should
be able to find it at C:\Windows\Temp. Once you get there, delete all files prior to
today's date.
Cleaning Temporary Internet Files : Temporary Internet files are another chronic
space-waster. From the Microsoft Internet Explorer 5.x Menu, select Tools/Internet
Options. On the General tab, press the Delete Files button under the Temporary
Internet files header. In Netscape Navigator, select the Cache entry under Advanced
options and clear the cache.
If you want to boost the performance of your hard disk, then click on Start and then
click on Settings > Control Panel > System. Now this will open Window by
name of System properties. Click on performance Tab and then on File
System. Look for the troubleshooting option and click on it. Now check the box
disable synchronous buffer commits. This setting will boost the performance of your
hard disk.
CD ROM
Similarly, you can also boost the performance of your CD ROM. For improving the
performance of CD ROM, click on start and then click Settings. Now click on
Control panel> System> Performance. Then select File System and CD ROM
tab. Move the supplemental cache size slider to the right to allocate more RAM
for caching data from the CD ROM drive or to the left to allocate less. Doing
this will definitely improve the performance of your CD ROM.
Clean up Memory Cache
Normally, people believe that by not clearing the memory cache and disk cache they
are doing the right thing. However this is not true, since the memory cache and disk
cache has a limited hard disk space. So if you do not clear it up regularly, the
browsing will become slow. It can also impact the overall performance of your PC if
these files are not cleared from the disk cache and memory cache. For clearing your
memory cache and disk cache click on the edit menu in Netscape Navigator window
and then click on Preferences sub menu. Now this will open Preference window on
your computer screen, click on the advanced Tab. And this will decompress the
various options. Click on the first option cache and then clear the memory cache and
disk cache.
22. Watermark Your Documents
Creating you own watermark for professional looking documents is pretty simple in
Word 2000/2003. First go to View > Header and Footer and click on the Show/Hide
Text toolbar button located on the Header and Footer toolbar (insert icon image).
This should temporarily hide the text. Now you can insert a graphics object using
Computer related Tips & Tricks
Page 23 of 26
Clip Art, Word Art or even AutoShape. Place the graphics where you want it to be
seen, and adjust the colour of the watermark by right clicking on the object and
choosing properties.
23. Convert Tables to Plain Old Text
