2. Set a Short Timeout

Using the keyboard shortcut is great because it locks your computer immediately. If there’s no delay, nobody can jump onto your computer in that window of time before it locks. Setting a short timeout until Windows automatically locks is a good backup option for those times when you forget to hit the shortcut, though.
