I was gonna buy a Windows 7 upgrade disk oday but they only had 64 bit. But I already have the 32 bit disk, I only need a key. So I'm just wondering if the 64 bit upgrade disk key will work with my 32 bit disk.
Doesn't the upgrade come with both 32 and 64 disks?
And yes, the keys are interchangeable between 32 and 64 bit versions on vista and 7, but not XP.
