If you have this little trust then for these people that are staying in your home then I would suggest not allowing them into your home at all.

How can you stop them from turning on your hot water and leaving it running all day while you aren't home?

How can you stop them from turning on all your lights?

How can you stop them from cranking your thermostat?

How can you stop them from peeing in your ice cube tray?

The fact is you either trust them or you don't. Your options are to un-invite them OR lock your computer up in your room and if they NEED to use a computer take them to an Internet cafe.

If it were me I would install Mint 7, then install Sun's VirtualBox, then install windows in that, then just leave the virtual machine running and they can use that and you can reset it's state each night.

The advantage of this last solution is you get to use Mint 7 which is very nice.
