Default Behavior

Windows Firewall is a Win32 service. In Windows 8 it is starting automatically during the operating system startup. Then the Windows Firewall service runs as NT Authority\LocalService in a process of svchost.exe, sharing it with other services. If Windows Firewall fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the MpsSvc service hasn't been started.

Dependencies

Windows Firewall can't start, if any service from the list below is disabled or not available:

Restore Default Startup Configuration for Windows Firewall

1. Select your Windows 8 edition and update pack, and then click Download.

2. Save the Win8_MpsSvc_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The MpsSvc service is using the mpssvc.dll file that is located in the %WinDir%\system32 folder. If the file is corrupted or deleted, you can put it back in there.
