Here is what I would like to be able to do. -Always revert back to a fresh install of my system except for one folder that I could keep files in that would always be accessible. -Start a "new image" and install a program and use it for more then 1 session(many) -Start another image and install programs on it. -Bounce between these images somewhat easily Would Comodo Time Machine be able to do this? any other recommendations? Was thinking Returnil but it doesn't seem like I can save sessions with that.
