      • Your computer needs to be signed into a Microsoft account for this to work. If you only use a local account, then you cannot lock or find your device.
      • For the lock to be more effective, make sure to also set an admin BIOS password to help protect against Windows reinstallation.
      • Keep in mind that administrators will still be able to log into a locked computer. Make sure that you don't give an administrator account to anyone that you might want to lock out of the computer.
