Help - VMWare or Virtual PC

I am trying to set up a test environment where I can do the following ; a) have XP and Vista and Windows7 installed on my PC. (I have already got XP and Vista installed as dual boot) b) through either Virtual PC or VMWare be able to have clean OS environments to test installation of software. * After each test I want to be able to have a clean OS again with minimum fuss and effort, ready for the next build test of the application. There must not be any registry entries, drivers, etc etc left, it must be a clean OS. Looking for assistance in ; i) which app do I use ii) how do I set it up I'm technical so it will be easy for you, I just need some guidance and overview. thanks ## Deliverables 1) All deliverables will be considered "work made for hire" under U.S. Copyright law.
