How to Temporarily Lock Your PC if Someone Tries to Guess Password

Both Windows 10 and Windows 11 provide users with many security settings that are not yet discovered. You can make some little changes to avoid unauthorized access to your Windows device.

For example, you can temporarily lock your Windows PC if someone tries to guess your password. If you do so, your Windows device will be locked automatically after several incorrect password attempts on the lock screen.
