Default Behavior

Windows Licensing Monitoring Service is a Win32 service. In Windows 7 it is starting automatically on the operating system startup. 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, Windows 7 attempts to write the error data into Event Log and restart the computer, using the Last Known Good configuration. If the Last Known Good configuration is not valid, Windows 7 startup ends with a Stop error. If you remove or disable the WLMS service, Windows 7 won't start.


Windows Licensing Monitoring Service is unable to start, if the Software Protection service is stopped or disabled.

1. Run the Command Prompt as an administrator.

2. Copy the commands below, paste them into the command window and press ENTER:

sc config WLMS start= auto

3. Close the command window and restart the computer.

The WLMS service is using the wlms.exe file that is located in the %WinDir%\system32\wlms folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
