That error started when I tried using msconfig to try to determine the cause of another problem.  I had rebooted several time without changing anything, 1st setting it to run with the basic drivers, then whatever the next option was.  That's when it started.  I thought it would be OK when I went back to a normal startup, but at that point it was broker.

The good news is that I had a restore checkpoint from a few days earlier right after the WIn 10 Anniversary updte.  I did a system restore, and the problem went away.   I don't think I'll ever try using msconfig again!.
