How to Enable / Disable Lock screen in Windows 10
The lock screen is the one you see when you lock your computer (or when it locks automatically after you haven’t used it for a while). The lock screen will also show up at start-up, logged out, and left idle for a minute. You will need to remove the lock screen to see the login screen and log into Windows. Users can turn off the lock screen by touch, keyboard, or by dragging the mouse up.
This guide will show you how to enable or disable the lock screen to make the login screen visible to all users in Windows 10.
You must be logged in as an administrator to be able to enable or disable the lock screen.
