The following steps worked for me ...
- ctrl-alt-del
- select Task Manager
- in Task Manager, select File then Run new task
- type "explorer" in the box next to "Open"
- click OK
now you should get your desktop back, I'd wait a minute or two, then
- reboot
- logon
steps 6 and 7 may be a little slower than usual
- desktop appears as normal
I hope this works as well for you as it did for me.
Thanks man saved my computer
