I replaced my motherboard and my old activation key would no longer work. I bought a new key from GKeys24 and received it within an hour. Went to the Windows Activation settings, clicked "Change product key", entered the key from GKeys24, and Windows is activated!!! I didn't need to re-install Windows.
