Removed KB4480970 according to other reports, but now the server is stuck at configuring updates 100% for last 10 minutes.  Waiting...

Reports of that registry change fixing Windows 7.  But so far nobody reporting successful Server 2008 R2 fix.
Server is locked up with spinning circle.  No mouse movement.

Just as I typed that, the server logged in.  This resolved the problem for everyone so far.
Workstations had to restart first (Not just a log off/log on).
Your help has saved me hundreds of hours of internet surfing.

So far adding the registry entry has fixed all computers.  Including the servers in which I have reinstalled the KB4480970, and Windows 7 file servers with KB4480960.  At this time, that is the best solution available.
