OK, I will help u, This - http://www.snapfiles.com/opinions/ShadowSu...adowSurfer.html http://www.snapfiles.com/reviews/ShadowSur...adowsurfer.html ShadowSurfer allows you to Undo all changes made to your system during a ShadowSurfer session. Once ShadowSurfer is activated, you need to reboot your PC and whatever changes take place while the program is activated, can be completely undone, returning your system to the state it was before ShadowSurfer was activated. You can activate the session for as long as you wish, and deactivate it easily from the system tray. The session can include all or just selected drives, whichever drives are selected - all data that was created during the session will be completely eliminated. This includes any software installed, browser history, cookies etc, as well as any other changes. Beware that this also includes email and other documents that were received during the session (if they were saved to a ShadowMode drive). ShadowSurfer can be a very effective and easy to use way to temporarily use your system in a shadow mode, however you should be fully aware of the consequences, in order to avoid unwanted data loss. A bright desktop wallpaper clearly alerts you of the ShadowMode while it is activated.
