I am looking for a software that will completely kill any changes made to my system every single time I log off. The type that I am looking for is what USA Libraries use. They set up the computer with everything that they want on it, like Internet Browsers, Office - Messagers and other "generic" programs. Then they somehow take a snapshot of that state and freeze the computer there. When any guest logs on they can do whatever they want with it but when they log off, everything that they did has been reversed.... like it never happened. I am NOT talking about system restore because that will leave a LOT of stuff. The library comps even delete files like jpgs that you save. The closest thing that I have found is RollBack RX, but it seems like a product meant as an enterprise solution. Does anyone know of one that I could install on a new machine? Looking for something low cost or free because I have to buy a new machine to run it on.
