Hi guys i want to buy a good used laptop with not activated windows 10. I have a Windows 7 Pro key on my old laptop. Can I use the one used for this?
Usually not. But it can work.

I activated my Windows 10 with a normal Windows 7 key.
Just go with the Microsoft Upgrade Tool! I recently did it with a 10 year old Samsung laptop!
