If your desktop, laptop, tablet, or Surface is lost or stolen, use the Find my device feature to locate and lock it remotely.
Find my device uses your deviceâ€™s location data to help you find your device if you lose it. Find my device allows an administrator of a Windows portable device, such as a laptop or tablet, to identify the location of that device from account.microsoft.com/devices. To use this feature, the administrator needs to turn on the location setting for the device and sign in to Windows through a Microsoft account. This feature will work for the administrator even if other users have denied access to location for all their apps. When the administrator tries to locate the device, users will see a notification in the notification area on the taskbar.
If you locate your device and want to prevent anyone from using it or seeing your files, you can lock it remotely.
When you remotely lock your Windows 10 Device, it will sign out any active users and disable local users. Administrators with permissions will still have access to sign in to and unlock the device, but unauthorized access will be blocked. Your device will be locked and location tracking services will be enabled. The lock screen will show a message you created. You will get emails for device update sent to your Microsoft account email address.
This tutorial will show you how to remotely lock your Windows 10 computer online using the Find my device Microsoft service.
