There is no unlock function for a Windows device that was remotely locked. The supported way to regain access is to reset the PC or perform a clean installation of Windows.
A reset can be started from the sign-in screen:
- Press and hold Shift.
- Select Power > Restart.
- In Windows Recovery Environment, select Troubleshoot > Reset this PC.
If personal files are important, try backing them up first from Windows Recovery Environment before resetting:
- From the sign-in screen, select Power.
- Press and hold Shift, then select Restart.
- Go to Troubleshoot > Advanced options > Command Prompt.
- Type
Notepad.exeand press Enter. - In Notepad, select File > Open.
- Use the file dialog to copy files to a USB drive.
A clean installation removes files, apps, and settings. A reset may offer an option to keep personal files, depending on the reset options available.
