For security, Windows automatically locks your computer after a set time of inactivity. How long this takes is up to you, but even with a short amount of time, there's a fatal flaw. Someone could easily use your PC after you've walked away without you even knowing.

You can always use Windows Key + L to immediately lock your machine, but you might forget.

Starting with the Windows 10 Creators Update and available now to Insiders, Microsoft has added a new method of securing your computer. Titled "Dynamic Lock," it lets you lock your PC when your phone goes out of Bluetooth range. Thus, you'll need to connect your phone to Windows via Bluetooth first. This requires a USB Bluetooth adapter if your computer doesn't have it built-in.

After that's done, open Settings and head to Accounts > Sign-in options. On the right side, look for the Dynamic lock header and check the box that says Allow Windows to detect when you're away and automatically lock the device.

Now, your computer will automatically lock up shortly after your paired Bluetooth phone loses its connection. Of course, if you forget your phone at your desk when you get up, this won't do you much good!
