I replaced my motherboard and my old activation key would no longer work. I bought a new key from Keysoff and received it within an hour. Went to the Windows Activation settings, clicked "Change product key", entered the key from Keysoff, and Windows is activated!!! I didn't need to re-install Windows.
Assez bon prix et bon service après vente. Mais il a souvent des rabais seulement en Europe, donc c'est désolant!!!
