I have at least one unused Windows 7 key that isn't currently in use on any machine (it was a retail key used on a HTPC I've since got rid of). I don't have any spare PCs to put it on and don't want to put it on a dual boot for the sake of upgrading it.
Is there anyway to register a 7 key as upgraded to 10 without installing Windows?
