Sorry for the long title.

Rebooting will take too long, switching users is not an option, I have 2 hard-drives, the other one will be available and has compromising files too ~~(read secret dirty porn)~~.

I was thinking about a virtual machine that I can trigger with a key press combination or something.

* Windows Vista
* 4GB Ram
* Core 2 Duo

The other OS can be any operating system that most people use (windows xp for example), probably I'll not be able to look at the screen all time to see if the person got access to the real OS.
