After I restarted my PC, for it asked me that made some updates and took a while setting the updates, I got stuck in the Login process.
I've hit CTRL+ALT+DEL chose for Task Manager and the display got black with nothing else but Task Manager window.
I've rebooted in Safe Mode and things got back again, just in Safe Mode. When I turn back in Normal Boot -> Blank Screen after inhibit the long waiting Login Process.
I can't System Recovery cause it was turned Off. I can't Reset PC cause I have a lot of Apps with configurations in them.
What should I do to recover my Desktop functionality?
