As a security precaution, it’s always a good idea to configure your Windows 10 PC to automatically get locked when you are away from your PC. Windows 10, like earlier versions, supports locking PC using Windows logo + L keyboard shortcut but most users don’t use this nifty feature when moving away from their PCs. If you also forget locking your PC when moving away from it, you can use the automatic lock functionality. There is an option in Windows 10 which automatically locks down your PC after a certain period of inactivity. For instance, you can make Windows 10 to automatically lock the PC after a minute of inactivity. That is, if you do not move the mouse, touch the touchpad or screen (if equipped with touch screen), or press any key on the keyboard for a minute or specified inactive time, Windows 10 automatically locks the PC and displays the lock screen. Of course, you should set a user account password before even thinking about enabling auto lock.
