Upgrade a Win 10 home OEM to Win 10 Pro OEM with Win 10 Pro OEM Key?

Hi shockwaveriderz

If you previously used that Windows Pro OEM licence on another PC, you cannot use that on your new laptop, that licence will be tied to the original motherboard

If you have not previously used that Pro OEM licence, you can use that on the new laptop, that licence will then replace the Home OEM Key on the motherboard of the new laptop . . .

 

Two OEM licence keys (different Windows versions) on one PC

Hello,
I'm in the process of building another PC and I want to know if it's possible for two versions of Windows to reside next to each other legitimately. I would have windows 7 and 10 as a dual-boot system. So if I buy OEM keys and activate them would one de-activate the other? I know that OEM licence keys are bound to the mobo and are irrevocable. Any advice is greatly appreciated. Thank you.
