So this morning i was greeted to my extenders connecting and constantly rebooting. Lucky enough it seems to have already been acknowledged at TGB as the new KB updates that came through on Dec 9th, it was indeed KB3004394 for me so I removed and marked hide until a better solution comes along. Below is the link discussing other issues like with playready because of this update as well. I didn't have playready issue just my extenders restarting. I removed only the KB3004394 leaving all other updates installed my extenders work, live tv works, recorded copy protected content works. http://www.thegreenbutton.tv/forums/viewtopic.php?f=5&t=8212
