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.


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

Restore Default Startup Configuration of Windows Firewall

Before you begin doing this, make sure that all the services on which Windows Firewall depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

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

sc config MpsSvc start= auto
sc start MpsSvc

3. Close the command window and restart the computer.

The MpsSvc service is using the mpssvc.dll file that is located in the C:\Windows\system32 directory. If the file is removed or corrupted, read this article to restore its original version from Windows 8 installation media.
