Change Activation Product Code
I have tried to change the product key using either my Windows 8 or 8.1 Pro 64 bit product keys. But every time i go to change product key, and put the new key it, and run ShowKey Plus, it shows the same old product key.
Is there a simple way to clear the UEFI of the old key completely, so I can do a clean install, using either of the above product keys?
