How to Protect your Laptop with Windows 10
From the Start menu, click Start and then choose Update & security and Find My Device. Click on Change to activate the feature—your laptop will then send its current location back to base on a regular basis, assuming it’s connected to Wi-Fi and has enough battery juice left. Note that you need to be signed in as an administrator to switch this feature on.
Go to https://account.microsoft.com/devices on any computer and sign in using your Microsoft account to find out where in the world your laptop has gone—any desktops you’re running Windows 10 on are listed here too, though the tracking feature only works on laptops and tablets (and as yet there’s no option to ping or lock your computer remotely). Click Find my device to see your laptop on a map.
Note: Feature is only available in Windows 10.
