2. In the Command Prompt, type the following command and press Enter: netsh advfirewall reset
3. This command will reset the Windows Firewall settings to their default values.
4. After the reset is complete, restart your computer for the changes to take effect.

Reinstalling the Windows Firewall Service

If resetting the Windows Firewall doesn’t resolve the issue, you can try reinstalling the service. Here’s how:

1. Open an elevated Command Prompt as mentioned in the previous section.
2. In the Command Prompt, type the following command and press Enter: sc config MpsSvc start= auto
3. This command will set the Windows Firewall service to start automatically.
4. Next, type the following command and press Enter: net start MpsSvc

Using the Windows Firewall Troubleshooter

Microsoft provides a built-in troubleshooter for Windows Firewall issues. You can download and run the troubleshooter to automatically diagnose and fix common problems. Here’s how:

1. Download the Windows Firewall troubleshooter from the official Microsoft website.
2. Run the downloaded file and follow the on-screen instructions.
3. The troubleshooter will scan your system for Windows Firewall issues and attempt to fix them automatically.
4. If the troubleshooter is unable to resolve the issue, it will provide you with additional troubleshooting steps or suggest further actions.

Checking for Malware Infections

In some cases, malware infections can interfere with the proper functioning of the Windows Firewall service. If you suspect a malware infection, you should scan your computer with a reliable antivirus or anti-malware software. Here’s how:

1. Download and install a reputable antivirus or anti-malware program on your computer.
2. Run a full system scan to detect and remove any malware infections.
3. After the scan is complete, restart your computer and check if the Windows Firewall service is working properly.

If the antivirus or anti-malware software detects and removes malware, the Windows Firewall service should function normally after the restart.

Checking for Conflicting Third-Party Firewalls

If you have installed a third-party firewall or security suite, it may conflict with the Windows Firewall service. To resolve this issue, you can try disabling or uninstalling the third-party firewall. Here’s how:

1. Open the Control Panel and go to “Programs and Features”.
2. Locate the third-party firewall or security suite in the list of installed programs.
3. Right-click on the program and select “Uninstall” to remove it from your computer.
4. Alternatively, you can open the third-party firewall or security suite and look for an option to disable the firewall component.
5. After disabling or uninstalling the third-party firewall, restart your computer and check if the Windows Firewall service is working properly.

If the Windows Firewall service starts working correctly after removing the third-party firewall, you can consider using the built-in Windows Firewall as your primary security solution.
