Sandboxie 3.02

Sandboxie allows you to run your browser, or any other program, so that all changes that result from the usage are kept in a sandbox environment, which can then be deleted later. This allows you to remove traces of your internet or PC activities, as well as reverse any changes to your Favorites, home page, registry and more.

Even files that were downloaded during a sandbox session will be wiped after the sandbox is cleared. The program runs in the system tray and if you want to start a sandboxed session simply launches your browser, or any other program via the tray icon, rather than the regular way.
