Windows 10: Is it possible to deactivate from one computer and using the same product key on another...

Hi, is it possible to deactivate from one computer and use the same product key on another computer? The device I'm deactivating has Windows 11 and I'm gonna try to use the key on a Windows 10 one.

Uninstall Product Key and Deactivate Windows 10


Deactivating Windows will not remove it from Microsoft's activation server.

It just simply deactivates Windows on the PC itself. This would only be helpful if say you're giving or selling the computer to someone, and don't want it to be activated with your retail product key.

You would only need to either uninstall or deactivate Windows on any other PC that you plan on using the same retail product key (license) on a new PC.

I dont get how that works because how does microsoft know you havent just used your product key on a new computer and your still using the old computer with the same product key, if you get what im saying. Surely you need to deactivate it so they know your not using the same product key on more than one computer.

Or is it tied to your microsoft account or something?

 

Deactivating Product Key on Old Computer to use on New

I recently inquired a new computer that is extremely faster than my old one. (i am using Parallels on Mac's)

I supposedly deactivated the product key on my old computer, (it said that it successfully deactivated). On the new computer, when I enter the product key it says it has already been used on a different computer.
