A new feature in Windows 10 is the ability to locate a missing device. Want to check you left your Surface at the Office and not on the train?- here’s how.

Step 1- Make sure you’ve updated to at least the November 2015 build of Windows 10 (v1511, 10586) using Windows Update.

Step 2- Go to “Settings” and choose “Find My Device” from the left hand menu. If it says “Find My Device is off” then click on the “Change” button and toggle the switch.

Step 3- Visit http://account.microsoft.com/devices and sign in, you should see your device listed- click on the “Find my device” link.

Step 4- You can see where your device was last seen on a map.
