CCleaner is a freeware system optimization tool for PCs. It removes unnecessary junk from your computer allowing it to run more efficiently and securely. It contains two essential tools: 1. File Cleaner This removes files that are not needed by your system, such as: temporary files, internet cache files, log files, deleted files in the recycle bin, and many more. The options for what to remove are covered by the first two tabs on the left of the main window: Windows and Applications. 2. Registry Cleaner This scans your registry and highlights issues that may be causing problems. Once scanned you may select the issues and fix them. You will be offered the chance the backup any changes as well. The options for what to scan are listed on the third tab "Issues" on the main window. Why should I clean my system? Do you remember how fast your computer was when you first got it? This is because you hadn't yet installed all those demos and utilities that you no longer use. Most of these programs leave behind temporary files and registry entries, even when uninstalled! Additionally your operating system records every visit to every website; every time you open a document, and a lot more. Do you want people to be able to find out this information? Even if you don't mind other people knowing what websites you visit, your internet browser can save personal information about you, such as your name, address, date of birth, passwords and credit cards numbers. Luckily CCleaner will remove all of these!
