I currently have two desktop computers at home.
This computer has windows 7 home premium x64 installed.
I have purchased a Windows 7 pro x64 OEM CD and key, and I want to upgrade this computer to pro.
My question is what happens to my home premium key once I do the upgrade, as I would like to upgrade my second machine running XP, to windows 7 home premium, using the key that is on this computer.
I was told the old key dies with the current machine once I upgrade. I have just spent money purchasing two Windows 7 OS, why cant I re-use it on another machine.
Can someone please advise & enlighten me :P
