Deep Freeze from Faronics wipes clean all changes made to your hard disk when you reset the machine. What I liked the most about Deep Freeze was that the system was perfectly stable and there was no increase the bootup time, unlike other software I tested, such as CleanSlate and GoBack.

You can do anything you want – Surf the net, install doubtful software, change registry settings – And it will be wiped clean when you reset the system. In fact, you don’t even need an anti-virus or anti-spyware program, if you are using Deep Freeze. To put it in a nutshell – Once you install Deep Freeze, the only thing that can affect your hard disk is if you take a hammer and smash it to bits.
