One of my customer today that said their machine did the a windows update and afterwards the login screen is gone. After checking the machine, I confirmed when I do a “CTRL+ALT+DEL” on the login screen, their no user listed at all, just the wallpaper and the power options on the bottom right.
First thing to solve the problem I tried to do system restore But unfortunately the PC didn’t had any system restore, revert update (couldn’t revert, said it was past the 10 days), uninstall quality update didn’t do anything and bypassing the windows 10 login screen still causes it to get stuck.
Only option I had was reinstall the PC as reset the PC to keep programs/files failed as well. I am guessing the windows 10 update didn’t install correctly or something conflicting it since it worked in safe mode but spending a few hours, it wasn’t worth it after that to try fixing a broken windows.
