@murphy78 "Offline" has dual meaning , yes can be phone because it would Force the phone prompt but also in my case I meant "No Internet Connection" without having to do a phone in.. @cuesporttech If you get Success! after doing slmgr.vbs - ipk You don't need to do steps 8-11! just logoff and back on or reboot then connect to net and should say "validated" if done right.
