Error Code 0x80070424 with Windows Firewall and "Base Filtering Engine Service" Not available in services database list.

Recently, many customers reported the Windows Firewall issue. This seemed to be caused by a wide spread malicious application.


The error message "Windows Firewall can't change some of your settings. Error code 0x80070424" will pop up when you try to change the Windows Firewall settings. In the meantime, when you restart the system, it might pop up an error saying that "Base Filtering Engine Service" could not be found in the system.

Please note that the same error code could pop up when you try doing anything in Windows Defender.


Download the registry files (You can also export HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\BFE from another working Win7 PC)


Launch and import them to registry

Restart your PC

Now,open RUN and type

regedit and click ok

go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\BFE

Right click on it-permissions

Click on ADD and type

Everyone and click ok

Now Click on Everyone

Below you have permission for users

Select full control and click ok

Now,open RUN and type services.msc and click ok

start base filtering engine service and then windows firewall service

Good luck

  • you,...yes,you... are completely awesome!!!!!

  • Thank you so much!  Worked like a charm!

  • Thanks.

    This put BFE back on the services list and running.  However, I am still left without Windows Firewall on the services list.   Do you have a similar reg file I can use for the firewall?

  • Thanks for the BFE! Now running and listed in the services list again! I agree with pb, also am having no Windows Firewall on the services list. Still having Windows Firewall error code 0x80070424 which is also not in the services list. Could you have a reg file for this??

  • you have to download both for the registery (there are two separate links).

    I now show then both in my registery, however it wont allow me to turn them on. I did add "everyone" to the permissions. Does this sound like a permission problem?

  • I follow all the steps. It works perfectly.

    Thanks so much.

  • It is not working fr me While trying to change the  window firewall settings it shows erroe 1068.

    Wat to do??/

  • After importing to the registry and rebooting, windows starts to black desktop and mouse cursor (no explorer/login screen), and nothing else - have to revert the changes to get back to functioning desktop.

    Windows 7 x64

  • absolutely perfect. I had error code 0x6D9  without being able to access firewall controls. This fix was spot on. Follow the directions exactly. My system: Vista x64. Thanks a bunch. I was gonna reformat next.

  • It is really great !!. It works awesomely for me as well.

    Thank you so much

  • Worked like a charm.  Downloaded and installed both reg files.  Rebooted and made regedit changes.  Firewall now working again.  Thanks.

  • Worked great! However Windows 7 users ignore the last part after set full control for both BFE and MPSSVC Reg files and reboot like vwvanman above suggests. Make sure to set permissions to both Reg files, follow the same process for both.  

  • You are truly amazing!  Thank you EVER so much!! :)

  • This is a great walk-through! This has been giving me a headache for 2

    weeks!!! Many thanks!

  • you are a god. i have been tampering with this for a while now. thank you
