Default Behavior

Windows Firewall is a Win32 service. In Windows 7 it is starting automatically on the operating system startup. Then the Windows Firewall service is running as NT Authority\LocalService in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Windows Firewall fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the MpsSvc service is not running because of the error.

Dependencies

Windows Firewall is unable to start, if at least one of the following services is stopped or disabled:

Restore Default Startup Configuration for Windows Firewall

1. Select your Windows 7 edition and service pack, and then click Download.

2. Save the Win7_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 changed, damaged or deleted, you can restore its original version from Windows 7 installation media.
