Yes, Go Giants!

You can install it on your desktop or laptop. The installation is pretty simple, the only decisions you need to make are how much disk space you are going to allocate to each session. Other than that, it basically creates another computer on your computer. If you install a rouge program in one of the sessions all you have to do is to delete it and start over. In an earlier version of Virtual PC (2004 I think) I had a Win 95, Win 98SE, WinMe sessions that I used for software testing. Unless you have mega amounts of memory and disk space I won't recommend more than two sessions.
