When you move away from your Windows 10 PC it will get locked automatically by a feature called Dynamic Lock. It can be activated with the help of your smartphone.
Dynamic Lock in Windows 10 is a very helpful feature when we are using our PC in any public place or Office. Suppose we forget to lock our PC when walked away from it. Then anyone can snoop into the PC until it goes to Lock mode by its own. This can be prevented from happening by activating the Dynamic Lock feature in Windows 10. Actually, it is being done through pairing your Smartphone with PC. Once the Dynamic Lock is activated, PC detects the presence of the paired smartphone. When you moved away from the computer with your smartphone, Dynamic Lock feature locks your Windows 10 PC.
Before activating Dynamic Lock feature by using your smartphone you should ensure that PC is running on Windows 10 Creators update. To verify this, right click on the start button. If you see Settings option in popup menu you can assure that PC is with Windows 10 Creators Update. Instead of this Settings option, if you see Control Panel, then you have to upgrade, which can be done through Windows Update from the Update & security screen under Settings.
Turn Bluetooth on PC & Smart Phone
Dynamic Lock feature uses Bluetooth connection to communicate between your PC and your phone. So you’ll need to make sure that Bluetooth feature is available and activated on your PC. Also, ensure that your phone’s Bluetooth connection is turned on as well. In Windows 10, turn on Bluetooth by clicking the Start button > Settings > Devices > Bluetooth & other devices. Once again confirm that Bluetooth is turned on.
In your iOS device, go to Settings > Bluetooth and toggle it on or swipe up from the bottom and tap the Bluetooth icon within Control Center.
As you know on an Android device, swipe down from the top of the screen for quick settings, and turn on Bluetooth if it’s not already enabled.

In this step, you’ll need to pair your phone with your PC if you haven’t already done so. To pair your Android device, go to the Bluetooth & other devices screen under Settings in Windows 10. Click on the button to “Add Bluetooth or other device.”
