Junior, I am guessing you are trying to script or image an unattended or "Light Touch" or "Zero Touch" build? In other words you are trying to utomate the instll of Windows right? If yes, then I highly recommend that you should purchase a Volume License and build a KMS Server. That way, you don't even have to worry about customising the PID key and the KMS server will automatically activate your Windows clients after they get domain joined. That is actually the whole point of what somebody referred to as the "generic" PID key which is actually KMS Client PID key. Your KMS server which has the KMS Server PID key will automatically search for clients on your domain and keep them activated on a recurring schedule. Might be a bit overkill for you but it is defintely a winner!
