Use any version of Windows 7 free for 120 days
 

I ran accross this today while surfing MSFN

This is a very good read here and useful incase you run past your 30 day limit on your bench. It also has a guide to make your Win 7 Ultimate ISO install any version of Win 7.

You must have your own keys tho in the end so no key hacking here

There's an easy way to stretch Windows 7's 30-day free-trial period to 120 days so you can determine whether Microsoft's new operating system meets your needs.

Very nice. Just so happens I think I got my hands on a copy of XP 64 and this will come in handy as I won't be able to activate it.
