Back to Windows Firewall?

Hi again...

"I also found these registry entries when enabling the firewall with Process Monitor running. You might check to see if you show them and what values they have.

HKLM\System\CurrentControlSet\Services\MpsSvc\Star tOverride

HKLM\SOFTWARE\MICROSOFT\Rpc\SecurityService\Defaul tAuthLevel"

I didn't find either of the locations shown in the lines above...



These show the open location and the indicated folders aren't present if I'm in the right place, I couldn't find any other HKLM location but these.

Here's another post addressing this problem.

The only problem is that the things I'm finding are for Vista and Windows 7 and I'm not sure that it's safe to use them with 8.

I can't tell you how many time I've wished I left well enough alone. LOL

I down loaded the registry files but haven't done anything with them.


Manual Fix
Download both the registry files
Windows firewall - Firewall
Base filtering engine - BFE

Launch them,You should get a UAC prompt now
Click YES & Restart your PC

Now,Press Windows+ R key and type

regedit and click ok

go to


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
If you still have this error Windows could not start Windows Firewall on local Computer. See event log, if non-windows services contact vendor. Error code 5.

Download and launch this key,click YES
Shared access
give full control permission to this key similar to previous one HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SharedAccess
Right click on it -permissions

Click on Add and type...

Everyone and select Full control
You should able to start firewall now

You may also be missing security center windows defender ,BITS and windows update services

Security center -wscsvc
Windows defender - windefend
Windows update - wuauserv

Launch them and click YES when you get a UAC prompt
Good luck

Hey Mike,

If the BFE service was not running, you should be getting a dependency error along with the access denied.

A good test would be to stop the BFE service then try to start the Firewall and see if you do. Then restart the BFE service. This would do two things. First make sure BFE is running and also test your permissions for that registry key.

Since the permissions for MspSvc.dll, MspSvc.drv and BFE are inherited from the CurrentControlSet key, you might compare its permissions with the ControlSet001 to see if they are the same. The test above may have already confirmed, but probably still good to check.

Since I got one of those annoying Link Back Posts on this for some reason I'll just update and say that after months of trying I have never succeeded in getting the firewall to start.

The COMODO firewall is working fine and I'm not going to mess with it anymore.

If the time comes when I have to reinstall I'll try again.
