Windows 7 firewall service won’t start


When you attempt to start the Windows 7 firewall service you receive the following error

Windows could not start the Windows Firewall on Local Computer. For more information, review the system event log. If this is a non-Microsoft service, contact the service vendor, and refer to service-specific error code 5.

If you look in the System Event Log, you will see event 7024 from the Service Control Manager

The Windows Firewall service terminated with service-specific error Access is denied..


This may be caused because the “NT Service\MpsSvc” account does not have adequate permissions on the following registry key



  1. In Registry Editor, browse to the key HKLM\SYSTEM\CurrentControlSet\Services\SharedAccess
  2. Right click SharedAccess, and click Permissions.
  3. Click Add.
  4. In the “Enter the object names to select” field, type “NT SERVICE\mpssvc”. Then click Check Names. The name should change to MpsSvc
  5. Click OK.
  6. Select Full Control in the Allow column.
  7. Click OK.

Applies To

Windows 7 (all versions) / Windows Vista (all versions)

  18. Worked for me, too. Trouble arose after removal of Internet Security 2013 virus. Firewall service initially did not even appear in Services. Got them back but firewall service would not start. This fixed after a few hours of searching for the cure.
