The following was posted (by me) on another Wilders forum but I think this is the more appropriate place to ask the question. I hope I am forgiven for posting the same thing in 2 locations. -------------------------------------------------------------------------- I have a paid licence for Returnil and I never use it and now that I know more than I did when I got Returnil (thats knowledge gained due to this forum I must say) I don't really understand the value of this sort of program. In my case I use RollBack Rx on my PC and I find it more effective to simply take a snap of my system instead of launching one of the lite-virtualization programs. Then I do whatever it is I would have done had I launched (say) Returnil. Once done I can simply keep going thus meaning whatever it was I was doing is kept. Or, I can take a new snap as I restore to the previous state, which would give me the ability to mount the later state as a virtual drive and have the ability to copy any download or modified files that occured during the virtualized period to whatever drive I wish (external or internal)(here I mean by virtualized period that period that would have otherwise been virtualized but was not). This gives you full and total control over what is kept and what is gotten rid of if you should decide to "clean-up after yourself" (so to speak). The light virtualization programs have too many parameters that need fussing with in order to accomplish what a RollBack type program does so much more easily and efficiently. And you can reboot without losing the virtual state or any of its content I suspect a full virtualization program would probably be even more effective but at some cost in terms of complexity (I must admit full V is on my to-do list, expect me to begin pestering you folks about it sooner or later). So why do these programs exist? Do they have a distinct purpose for being used on a computer that I am not aware of? Don't get me wrong, Returnil (and many of the programs in this class) is a fine piece of programing and it is very well supported,,,,but why? Oh, if you were going to say they can be used for browsing thus protecting the PC while surfing into areas that are "a bit - or a lot - more dangerous than most sites Sandboxie handles this very nicely and with little in the way of user settings to bother with, again a much simpler solution than a lite-V program. PS: sorry if I am a bit off tonight in terms of expressing myself, I have not had much sleep the last 4 days and I am a bit out-of-it, none-the-less I look forward to any comments on this. It is about furthering my education after all and what better place to do so than here.
