Windows Firewall is one of the built-in security features in Windows 11 that helps protect your PC by monitoring incoming and outgoing network traffic, blocking unauthorized connections, while allowing trusted applications to communicate over the Internet. However, software installations, malware infections, or accidental configuration changes can cause network connectivity issues such as VPN connectivity errors, file sharing issues, or apps not connecting. If you are experiencing such issues, learn how to reset firewall settings on Windows.  Clean Junk Files In Windows. Nearby Sharing Not Working on Windows

What Does Resetting the Firewall Do?

Resetting Windows Firewall removes all custom settings and restores the firewall to its original configuration.

This means Windows deletes:

• Custom inbound rules
• Custom outbound rules
• Blocked or allowed application permissions
• Modified network profile settings
• Advanced firewall configurations

After the reset, Windows automatically recreates the default firewall rules needed for normal system operation.

It does not remove your files, uninstall applications, or affect your Windows installation.

When Should You Reset Windows Firewall?

A firewall reset isn’t something you should do regularly. It’s mainly a troubleshooting step when normal fixes don’t work.

Here are some common situations where a reset makes sense.

1. Applications Cannot Access the Internet:

Sometimes programs continue showing network errors even though your internet connection is working properly.

If only certain applications fail to connect, damaged firewall rules could be blocking them.

2. Firewall Rules Have Become Too Complicated

Over time, installing software creates dozens of firewall exceptions.

If you’ve added many custom rules yourself and no longer remember what was changed, starting with the default settings can be easier than fixing each rule individually.

3. Malware Cleanup

Some malware changes firewall rules to allow unwanted connections. After removing the malware, resetting the firewall ensures those changes are removed.

4. Network Sharing Stops Working

If devices on your home network suddenly can’t find each other, incorrect firewall settings may be responsible. A reset most of the time restores normal network discovery and sharing.

5. VPN or Remote Access Problems

VPN software relies on specific firewall permissions. If VPN connections suddenly stop working after changing firewall settings, resetting may resolve the conflict.

Things to Do Before Resetting the Firewall

Although resetting Windows Firewall is safe, it’s worth taking a few minutes to prepare.

Write Down Important Rules

If you’ve created custom firewall rules for:

• Game servers
• Remote Desktop
• Development tools
• NAS devices
• Database software

make a note of them because you’ll need to recreate them later.

Check Installed Security Software

Some antivirus programs include their own firewall. If you’re using one, resetting Windows Firewall may not affect the firewall currently protecting your computer.

Save Your Work

A firewall reset doesn’t restart Windows, but some applications may briefly lose network connectivity. Saving your work first is always a good idea.

Resetting firewall settings on Windows 11 can be done through Control Panel, Windows Security, Command Prompt, PowerShell, or Windows Defender Firewall with Advanced Security.

How to Reset Firewall Settings on Windows 11 Method 1: Reset Firewall Using Windows Security

This is the simplest method and works well for most users:

1. Open Settings.
2. Select Privacy & Security.
3. Click Windows Security.
4. Open Firewall & network protection.
5. Scroll down and select Restore firewalls to default.
6. Click Restore defaults.
7. Confirm the action when Windows asks for permission.

Windows will immediately restore the original firewall settings.

Method 2: Reset Firewall from Control Panel

Many users still prefer the classic Control Panel because it provides direct access to firewall options.

Follow these steps:

1. Open the Control Panel.
2. Select System and Security.
3. Click Windows Defender Firewall.
4. Choose Restore defaults from the left panel.
5. Click Restore defaults.
6. Confirm the action.

This performs the same reset as Windows Security.

Method 3: Reset Firewall Using Command Prompt

If Windows Security isn’t opening or you prefer command-line tools, Command Prompt offers another quick solution.

Here’s how:

1. Search for Command Prompt.
2. Select Run as administrator.
3. Type this command: netsh advfirewall reset
4. Press Enter.

If the command completes successfully, Windows restores all firewall settings immediately. This method is particularly useful when the graphical interface isn’t working correctly.

Method 4: Reset Firewall with Windows PowerShell

Using Windows PowerShell, administrators can adjust and maintain firewall settings.

Open PowerShell as Administrator and run the appropriate firewall management commands available on your system.

Follow these steps:

1. Right-click the Start button and select Windows Terminal (Admin) or PowerShell (Admin).
2. Run the following command:

(New-Object -ComObject HNetCfg.FwPolicy2).RestoreLocalFirewallDefaults()

3. Wait for the command to complete.

Many IT professionals prefer PowerShell because it can be combined with automation scripts for managing multiple computers.

For most home users, however, the Windows Security app remains the simplest option.

Method 5: Use Windows Defender Firewall with Advanced Security

If you don’t want to reset completely, the Advanced Security console lets you review existing rules before deciding what to remove.

To access it:

• Press Windows + R
• Type: wf.msc
• Press Enter

Here you can:

• Review inbound rules
• Review outbound rules
• Delete unnecessary rules
• Disable specific rules
• Export firewall policies before making changes

This option is useful if only a few rules are causing problems.

What Happens After Resetting the Firewall?

After the reset, Windows goes back to its default firewall settings.

You’ll notice a few immediate changes.

Applications May Ask for Permission Again

Programs you’ve previously allowed through the firewall may display permission requests the next time you open them. You’ll need to approve trusted applications again.

Custom Rules Are Removed

Any manually created firewall rules disappear.

If you rely on specialized software, you’ll have to recreate those rules.

Network Profiles Return to Default

Windows restores the recommended settings for:

• Domain networks
• Private networks
• Public networks

This improves security but may require reconfiguring certain sharing features.

How to Check if the Reset Worked?

After resetting, verify that everything is functioning properly.

You can test a few things:

• First of all, open your web browser.
• After that, launch applications that use the internet.
• Then, check file sharing if you use it.
• Test your VPN connection.
• Once done, open Windows Security and verify that Firewall is enabled.

If everything works normally, the reset was successful.

Tips for Managing Windows Firewall

Once you’ve reset the firewall, it’s a good idea to keep your configuration simple.

Keeping these small things in mind can help:

1. Only allow trusted applications through the firewall.
2. Remove permissions for software you no longer use.
3. Keep Windows 11 updated so firewall improvements are installed automatically.
4. Avoid disabling the firewall unless you’re troubleshooting a specific issue.
5. Review firewall permissions every few months if you install lots of software.
6. Be cautious when software requests network access for the first time.

Following these practices helps maintain both security and performance.

Conclusion

If you’ve been dealing with strange network issues, resetting the firewall is one of those simple things that’s worth trying. It doesn’t take much time, and in many cases, it can fix problems caused by old or incorrect firewall rules.

After the reset, Windows starts fresh with its default settings, so you may have to allow some apps again the next time you open them. You shouldn’t need to make any other changes after that. If everything starts working normally again, you’re good to go. 

And if the problem is still not resolved, at least you’ll know the firewall isn’t what’s causing it. This will make the next troubleshooting step a little easier.
