First I bought a laptop with 10 pro. Then I got a PC from my brother, which didn't have a windows key. So it was shared between them twoIt didn't ask the windows key, just worked after my account. Now I got my second laptop, which had 10 pro installed. I linked that to my Microsoft account and upgraded it to windows 11 pro.When I check their product keys, they are all different. It seems that I got a free key from somewhere, even when I didn't.Now I am selling them all and I would like that they all have the proper windows installed. How do I know, which keys are real and which key is the sh

How to unlink a product key from the Microsoft account?

It is dead easy to remove the digital link from MS account. Simply change login to a local licence.

Then use your product key on new pc. If Windows complains key has already been used, use telephone activation and at step where it asks about licence, state it will only be used on new pc.
