The Windows Firewall service runs as NT Authority\LocalService in a shared process of svchost.exe. Other services might run in the same process. If Windows Firewall fails to start, the error is logged. Windows 8 startup proceeds, but a message box is displayed informing you that the MpsSvc service has failed to start.
Windows Firewall won't start, if the following services are stopped or disabled:
1. Select your Windows 8 release and edition, and then click on the Download button below.
2. Save the RestoreWindowsFirewallWindows8.bat file to any folder on your hard drive.
3. Right-click the downloaded batch file and select Run as administrator.
4. Restart the computer.
Note. Make sure that the mpssvc.dll file exists in the %WinDir%\system32 folder. If this file is missing you can try to restore it from your Windows 8 installation media.
