Write filters
Write filters provide a secure environment and can extend the life of your thin client by protecting it
from unauthorized and excessive writes to the flash drive. Write data is intercepted by the write filter
and cached in the RAM drive, and as a result, lost after the next reboot. There are two different types
of write filters available:
●
Enhanced Write Filter (EWF)—Protects the entire flash drive from writes
●
File-Based Write Filter (FBWF)—Allows you to specify files or folders to be excluded from
interception by the write filter
Only one write filter can be selected and active at one time. To save permanent configurations to the
flash drive, the write filter must be temporarily disabled.
CAUTION: Ensure that the write filter is enabled after committing necessary configurations to the
thin client flash drive. During normal operation of the thin client, the write filter must be enabled. Also
ensure that Page File is not enabled on thin clients with flash memory storage. Failure to follow these
required actions can void the warranty of the flash storage device. In the event of damage to the flash
storage device due to operation with a disabled write filter or enabled Page File, the damage will not
be covered by HP warranty.
Enhanced Write Filter
Using the Enhanced Write Filter command line utility
The EWF command line utility enables you to issue a set of commands to the EWF driver, report the
status of each protected volume overlay, and report the format of the overall EWF configurations.
To use the EWF command line utility, follow these steps:
1.
Select Start > Run.
2.
Type CMD and click OK.
3.
Enter ewfmgr c: <commands> at the prompt.
The following table describes the supported commands for the EWF utility.

Local drives
IMPORTANT: The write filter must be disabled for any configurations to be made permanent. See
Write filters on page 2 for more information.
The following local drives are configured on the thin client by default:
●
Drive C (flash drive)—This is where the operating system and software are installed. Writes to
this drive can be limited or restricted entirely by using a write filter.
CAUTION: HP recommends that you do not allow the available free space on the flash drive to
drop below 10% of the flash size. If the available free space on the flash drive drops below 15
MB, the thin client can become unstable.
●
Drive Z (RAM drive)—This is a virtual drive that is created from the system's physical RAM. This
drive will look and behave like a standard fixed disk drive, but it is created at system startup and
destroyed at system shutdown. Therefore, HP recommends that you do not store information or
data on this virtual disk drive.
The following items are stored on Drive Z:
◦
Browser web page cache
◦
Browser history
◦
Browser cookies
◦
Browser cache
◦
Temporary Internet files
◦
Print spooling
◦
User/system temporary files
You can use the HP RAMDisk Manager utility to configure the size of Drive Z. For more
information, see HP RAMDisk Manager on page 10.
TIP: HP recommends that you save files that you want to retain on a server rather than on the thin
client. By default, many software programs write cache files to the C drive on the local system. If you
must write to a local drive, configure the software program's settings to use the Z drive instead.
Local drives

Configuring logon settings
IMPORTANT: The write filter must be disabled for any configurations to be made permanent. See
Write filters on page 2 for more information.
By default, the thin client logs on as a user. An administrator must log on manually. Note the following
about using the manual logon method:
●
For a user account, the factory-default user name and password are both User.
●
For an administrator account, the factory-default user name and password are both
Administrator.
●
For security purposes, HP recommends that you change the passwords from their default
values. An administrator can change passwords by pressing Ctrl+Alt+Del and then clicking
Change a password.
NOTE: You cannot change the password while logged on as a user.
●
Passwords are case sensitive.
Alternatively, the thin client can be configured to log on to a specific user account automatically. To
configure automatic logon:
1.
Click Start > Control Panel > HP Logon Manager.
2.
In the Windows Logon Configuration dialog box, check the Enable Autologon box, type the
account credentials and domain name, and then click OK.
The configured account will be logged on to automatically during system startup.
TIP: To log on as a different user or as an administrator when automatic logon is enabled, simply
log off the current account to return to the Windows logon screen.
Configuring the system date and time settings
IMPORTANT: The write filter must be disabled for any configurations to be made permanent. See
Write filters on page 2 for more information.
You can use the Date and Time utility in the Control Panel to set the system date and time manually
or to configure the system to synchronize the date and time with an Internet server periodically.
TIP: You can also access this utility by clicking the clock in the Windows notification area and then
clicking Change time and date settings or by right-clicking the clock and selecting Adjust date/time
from the menu.
If you want to configure the system to synchronize the date and time with an Internet server, you will
also need to enable the Windows Time service, which is disabled by default. To do this, follow these
steps:
6
1.
Click Start > Control Panel > Administrative Tools.
2.
Double-click Services.
3.
Double-click the Windows Time service to access its settings. You can start the service manually
and configure it start up automatically in the future.
