Check Necessary Services
Windows Firewall depends on a few services for its operation. So the first thing you should do is make sure they are running properly. Here’s how you can do so and set the proper setting to run them automatically:Restart your PC and check if you still encounter the issue.
Restore Windows Defender Firewall Authorization Driver
Your Windows Defender Firewall uses the Windows Defender Firewall Authorization Driver mspdrv.sys to run properly. So, you also need to make sure this driver has no issues. Here’s how you can do so:Also, you can’t run these commands if the file is missing so check the location through the file explorer in such cases. If the file is missing or SFC can’t fix the corruption, you need to transfer a working copy from a different computer.
Reinstall Windows Firewall
You can also try reinstalling the Windows Firewall altogether to resolve any errors within. This resets any changes you made to the Firewall profile, however it is better than not being able to run this process at all. Here’s what you need to do:Restart your PC and check if the issue resolves.
Repair Corrupt System Files
We have already mentioned that the Windows Firewall service relies on many dependencies. So, if any one of such files is corrupt you will experience the above error. You need to run the System File Checker on all system files to check for and repair any potential corruption to prevent such issues. To do so,
Scan for Malware
By default, Windows is configured to have the proper settings and files for running Windows Firewall. So unless you made the unnecessary changes, any errors in the settings or files are likely due to some malware script.The above methods may help resolve your issue, but you need to detect and remove the malware to prevent the error from occurring again. Here’s how you can do so using the built-in Windows Security or Defender:

Many third-party antiviruses are responsible for blocking dependency services from starting. While they may actually contain malware or threats, usually it’s a false positive.Windows already contains a fantastic antivirus, the Windows Defender, so you don’t really need other security apps. If you still want to use them, you can try disabling them temporarily and see if the Windows Firewall service can start without any issues. However, make sure that your computer does not contain any threats before doing so.The process to disable the antivirus differs between the different software. So, we recommend checking the official website if necessary.
Set LocalService and NetworkService Users to Admin Group
You can also encounter this error if there are permission issues related to the LocalService or NetworkService groups. Windows Firewall logs on through the LocalService account so such issues prevent starting the Firewall.You can try creating a new user account to avoid this issue. However, if you want to resolve the problem in your original account, you can try adding the above users to the Administrators group which bypasses the original permissions. Here’s how you can do so:Restart your PC and check if the issue persists.
Perform a System Restore
If you have a suitable restore point where the Firewall could start without any issues, you can try restoring your system back to that point. This takes care of any registry errors as well as system file corruption that your system encountered afterward. To do so,
