Windows 10: Will removing my account from a Windows 10 device remove it's product key?

I got an old PC that had Windows 10 Pro and tried to upgrade my Windows 10 Home on my Gaming PC to Pro so I signed in on my Microsoft account on the older computer, but then after a bit of research I found out OEM keys cannot be transferred from one device to another. Will I lose access to the Pro key on the older computer if I remove my Microsoft account from it?

Hi,



Thank you for writing to Microsoft Community Forums.



I understand that you are facing issues while removing the device from your Microsoft account as it keeps popping back after removing.



It could be possible that the device was using OneDrive with the same Microsoft account and that might be the reason you are able to see the device listed under your profile. I would suggest you to remove the device from OneDrive
and see if that helps.



You can follow the steps to remove the device from OneDrive.

1. Login to
   https://onedrive.live.com.
2. Now on the left hand pane click on PC’s.
3. Now click on the devices that are listed under PC’s and on the right hand side click on
   Remove PC.

If the issue persists, please get back to us with the results of the troubleshooting steps to assist you further.
