Same thing is happening to me, the powershell command does nothing.
Just after making a post on G+ about how MS is killing the info on updates I came upstairs to find my PC with a black screen, unresponsive so I had to hard reset it and sure enough it finished Windows updates only to reboot while it was finishing up.
Now my Note, One Drive, etc keep crashing and I have a dead Start and Notification menu.
I said screw it to this "ad based OS" and went to do a roll back and well...I cannot do that because in MS's infinite wisdom they allowed their media creation tool to overwrite your much needed BT folder thus eliminating the ability to revert...bravo MS!!!
I loathe where MS is going now and want nothing to do with 10 anymore. :angry:
EDIT:
Actually...the only thing that works with a left click on my task bar is task view and show hidden icons.
Start, search, networks, volume, and notifications are unresponsive however I can right click on them.
When I try to do a refresh and keep my files it tells me everything needs to be reinstalled so what is the point.
This blows...
