Windows could not start the Windows Firewall on Local Computer

You might find this issue where when you try to turn on Windows Firewall it would say the service is not running. Then when you try to start the Windows Firewall service you may see this error message: Windows could not start the Windows Firewall on Local Computer with Error Codes 13, 1079, 6801, etc.

In this article, I’ll suggest a few tips to resolve this problem.

Windows could not start the Windows Firewall

Step 1:

This step is standard to fix most of the Windows-related issues. Yes, we have to run an SFC Scan to see if Windows could fix it by itself.

1. Go to Start under search type in CMD
2. Right Click and Run as administrator
3. Then type in SFC /SCANNOW and press Enter.

For further details check this article System File Checker.

Step 2:

If there is a permission-related issue, we have to give enough permission to those key.

1. Go to Start under search type in Regedit
2. If it prompts for an administrator password type it in
3. There go to Computer and right-click and click on Export
4. Under File name type in Regbackup and click on save

Then you have to give permission to the following keys:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Epoch

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Parameters\FirewallPolicy

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\SharedAccess\Defaults\FirewallPolicy

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dhcp

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Dhcp\Configurations

Right-click the key, and click Permissions. Click on Add. In the “Enter the object names to select field, type “NT SERVICE\mpssvc“. Then click “Check name.”

Click OK. Then click on Add again. Type in Everyone and then click OK.

Then select the account which appears in the list, and add the proper permission for it.

Under the Allow section put a checkmark on Full control.

When this is done, click OK and restart your computer.

If you’re getting access denied, Turn Off UAC via your Control Panel and try it again.

Step 3:

Sometimes Malware infections can cause the service to fail. So I would recommend that you run a full scan of your anti-malware. You may also download a second stand-alone scanner like freeware Malwarebytes, Emsisoft or the new Microsoft Safety Scanner and run a complete system scan in Safe Mode, to get a second opinion.

Step 4:

If your system fails to find any infection, the last thing left to do is to run a Repair Install on Windows most of one or more system files might have corrupted. Follow this post on how to run a Repair Install on Windows 7 or Reset This PC on Windows 11/10.
