When I lock the screen on Windows 8 using + L, the lock screen background image appears, and usually the clock is being displayed, and when you hit a key or Ctrl + Alt + Del, your login and a password prompt is shown.
However, sometimes the clock does not show at all, and pressing keys or Ctrl + Alt + Del will not present anything.
All you see is the Windows lock screen background image, no clock or anything.
I cannot even switch to standby or get the computer to shut down through the power button.
The only way to escape is to force-kill the power by holding the power button and restarting.
However, the mouse is still moving, and Caps Lock still turns the LED on and off.
How can I turn off this security-hardened lock screen that really locks anybody out ?
Has anyone even experienced this ?
