I recently built a new PC and I'm trying to use my Windows key that I used on my laptop. This key was originally Windows 7 or 8 (I'm not sure), it turns out that when I start the configuration of my new PC with the key I took from the registry of the old laptop, it tells me that I don't have Windows activated, I can't, for example change display settings.
The strangest thing is that I'm using the same @hotmail account on both machines but only the laptop seems to recognize that I'm using legitimate Windows.
At the moment I only have the key visible in the Windows 10 registry installed on the old laptop, I don't have the original Windows 7 key, so, how can I solve it?
I no longer want to have Windows activated on my old laptop, I want it on my new PC.
