Windows Licensing Monitoring Service is a Win32 service. In Windows 10 it is starting automatically when the operating system starts. Then the Windows Licensing Monitoring Service is running as LocalSystem in its own process of wlms.exe. If Windows Licensing Monitoring Service fails to load or initialize, Windows 10 attempts to record the error details into Event Log and restart the PC, using the Last Known Good configuration. If the Last Known Good configuration cannot be applied or working improperly, Windows 10 startup process halts with a Stop error. If you disable or delete the WLMS service, Windows 10 won't start.
