Hi,
I followed directions found here in community and they worked on most of the pc's I had the problem on except two.
Start computer and do a hard shutdown. (Start computer and when you see the Blue Spinning Animated Icon, Hold the power button and shut down. Repeat this three times. On the third try you will get to a window with more options. Go to Advanced and you'll
see System Restore. Go back to a restore point before you had the problem. I actually went back about a month. I then went in to service and stopped & shut down windows updates temporarily in hopes Microsoft will come up with a
fix. Other people in this thread recommend uninstalling and hiding certain updates. Hope this helps.
