I have two Windows licenses: WIndows 7 Home that was already installed on this HP and Windows 7 Ultimate that I had purchased and is currently installed on a Dell. I upgraded the OS on the HP to Ultimate (through the MS site), but it currently is not accepting my activation code probably because it's being used on the Dell.
What do I need to do to be able to 'transfer' the Windows 7 Ultimate activation code from the Dell to this HP?
How do I retrieve the Windows 7 Home key used in the HP so I can use it on the Dell?
I also tried finding Microsoft contact information, but that's a rather impossible task.
