Thus, if you have lost a laptop, there is a chance to find it, moreover, remote locking of a computer with Windows 10 can be useful if for some reason you forgot to leave your account, and it would be better to do it.

First of all, about the requirements that must be met in order to take advantage of the possibility described:

  • The computer being locked must be connected to the Internet.

  • It should enable the "Find My Device" feature. Usually this is the default, but some programs for disabling the spyware features of Windows 10 may disable this feature as well. You can enable it in Options - Update and Security - Find My Device.

    Find My Device


  • Microsoft account with administrator rights on this device. It is through this account that the lock feature will be executed.

If all specified is satisfied, you can proceed. On any other device connected to the Internet, follow these steps:

  • 2. A list of Windows 10 devices using your account opens. Click "Show Details" on the device you want to block.
