How to Change Lock Screen Clock to 12 hour or 24 hour Format in Windows 10
The lock screen is the screen you see when you lock your PC (or when it locks automatically after you haven't been using it for a while). The lock screen will also show at startup, and when you are signed out and idle for one minute. You will need to dismiss the lock screen to be able to see the sign in screen and sign in to Windows. Users can dismiss the lock screen using touch, the keyboard, or by dragging it up with the mouse.
The clock on the lock screen displays time in a 12 hour format by default.
