If location was disabled before the PC was stolen, Find my device cannot locate it.
What can still be done:
- If Find my device had already been turned on and the device appears under the Microsoft account devices page, check whether Lock is available at https://account.microsoft.com/devices.
- Reset the Microsoft account password for added security after locking the device.
- Check the device serial number under Info and support on the devices page, if the device is still listed.
- Report the theft to local law enforcement and the insurance company.
- If sign-in to the Microsoft account is blocked, use the sign-in helper tool.
Important limits:
- Find my device must be turned on before the device is lost.
- The account on the device must have been an Administrator account.
- Without location turned on beforehand, there is nothing further available through the Microsoft account to find the PC.
