I have a Windows 8.1 desktop machine which, as the title says, randomly enters in the lock screen.
The lock outs are not periodic and happen even when the user is working the computer.
My first thought was that the keyboard/mouse was faulty and would send random keystrokes to the OS (Win+L), but the problem persisted even with a different keyboard.
I have a table with the time of day when this occurred and matched against the event logs and there seems to be no pattern there.
Any ideas on what could be the problem?
