If I'm following this right, then I think Ace Modder's problem is that he upgraded a Retail Windows 7 key to Windows 10 expecting to get a Retail Windows 10 key from it - i.e one that he would be able to transfer from motherboard to motherboard.
But instead he has effectively upgraded his retail key to an OEM one, and has therefore tied it to a single motherboard?
