So, right around the Windows 8 release, Windows went to a system of only reading the BIOS for the key. With Windows 10, Windows went to a system of storing a fingerprint remotely, only leaving a generic key in the OS.
So the "key" for your Windows 8 install is/was in the BIOS of your old board, and the key for your upgrade was married to the configuration with your old board.
To put it another way, in this case, you are "attached to another object by an inclined plane, wrapped helically around an axis".
