Hi guys,

Unusual thing happened to my Optiplex 7070 sff. I am regularly installing all Windows updates. A few days ago I have installed the latest Windows update (cumulative updated for February). Today when I turned on my PC, I was able to log in to my account, but I can't start any programme - when I try nothing happens. I can only close programmes that start automatically, but can't even reboot my PC nor open task manager. I have to hold power button to shut it off. I have tried restoring to the earlier point, everything worked after that and when I rebooted PC again the same issue. This is not happening on my Lenovo laptop. I have tried repairing Windows nothing. However, I have enabled Admin account, and with it, everything works fine. Only my account doesn't work.

Tried three antiviruses, they found nothing. Also, dell support applications doesn't work (on either account). When I try to run to check for updates I get error, same when I scan for hardware changes.

Any suggestions what to do here?
