i use Windows xp Sp2. is there any software that will start with windows and make the session totally virtual . by virtual i mean that what ever changes made to the registry or programmes installed are nullified when the computer is restarted.so when the computer is restarted the previous session should not have existed.. hope your getting the idea .. its something like system restore. only problem with system restore is that some of the changes made during the session still remain .. so i was wondering if there is any other software that can be used to make a session totally virtual in other words that session never existed and the computer returns to its previous state.

not exactly sure but maybe this will help.
