(Thanks for Ratbag's suggestion)

I have trialed this Powershadow software for several days.

It can give you a virtual windows system to test new software.
No garbage file left after trial.

It is very simple and amazing.

Hard to describe in words,
take a look for yourself at http://www.powershadowsecurity.com
You won't regret!

Went to download it, but alas it says it is not compatible with Vista.
