Usage tracks are your fingerprints in your system. Whenever you visit a page with your browser, or just open any file, that information is stored deep inside Windows. In most cases that is very useful û if you want to open that file again, you can select it from a list instead of typing the whole filename or browsing the whole directory structure again.

But in some cases you may want to hide your activity, because spyware and internet attackers may use that information. Spybot-Search&Destroy can remove some of the most important and common tracks on your system.
