I've done online upgrade of Windows 10 Home to Pro on my Surface Pro 7. The license is associated to my Microsoft account.
I understand this upgrade license is not transferable to another PC because it's not retail license however it should still be valid for this PC even after resale?
Unfortunately it would require that I log in on the PC every time after factory reset which is not feasible after resale.
Is there some way to transfer this license to another account or convert it to a key?
