Lock on leave, wake on approach with Presence Sensing

Your PC will keep your data safe by locking the screen when you're not using it. When you walk away from your PC, the operating system will lock the screen to maximize security and battery savings. 

You can also customize how long it takes for your screen to dim and lock after you leave. 

Wake on approach is a feature that makes your device smarter and more convenient. It detects when you are near the device and automatically turns on the screen. This way, you can sign in and start using your device right away.
