When Microsoft released Build 15031 of the Windows 10 Insider Preview on February 8, 2017, it added a new OS feature for Bluetooth-equipped devices.
It’s called Dynamic Lock, and lets you control access to your PCs based on how close they — and your Bluetooth-paired phones — are to them.
That is, if the phone you’ve paired with your PC (it works for laptops, notebooks, tablets and desktops) is not found within radio range of your PC, Windows 10 turns off the screen and locks the PC after 30 seconds have elapsed.
Thus, Dynamic Lock makes a dandy new security feature in Creators Update, one that most business users (or their IT departments) will find worth turning on and using.
Setting up Dynamic Lock
To begin, you must pair your phone with your Windows 10 PC. To do this, open “Devices and Printers,” then click “Add a device.” Once the phone has been paired with your PC, you’ll see something like this under the “Devices” heading in this control panel widget (here, my iPhone is paired with my Dell Venue Pro 11 7139 hybrid tablet PC).
