How to Backup and Restore Microsoft Defender Firewall in Windows 11

Method 1Using Windows Security App

Windows Security app lets you backup Microsoft Defender Firewall settings without using any command-line tools. You can use this built-in menu to save your current firewall rules to a file on your computer. This protects your custom security rules so you can restore them later if your settings get reset or something goes wrong.

1. Click the Start button on your taskbar 🖥️.
2. Select Settings from the menu.

3. Click Privacy & security on the left side.
4. Find the Windows Security tile and click it.

5. Click the Open Windows Security button.

6. In the Windows Security app, select Firewall & network protection. You can also use this shortcut: Firewall & network protection.

7. Scroll down and click the Advanced settings link at the bottom.

To Back Up Your Settings:

1. In the window that opens, click Export Policy.
2. Choose where you want to save your backup file.
3. Give the file a name (it will be a .wfw file).
4. Click Save.

To backup Microsoft Defender Firewall settings, you need to use the Export Policy option inside the Windows Security interface. This process saves all your active firewall rules into a single file with a .wfw extension. You can store this backup anywhere on your computer and use it later to restore your exact security configuration.

To Restore Your Settings:

1. Go back to the Advanced settings window.
2. Click Import Policy.
3. Find your backup file and open it.
4. Your firewall settings will be restored.

Method 2Using Command Prompt or PowerShell

Administrator privileges are required for this method.

1. Open the Windows Terminal app as administrator.
2. Choose either the Command Prompt or PowerShell tab.

To Back Up Your Settings:

Using Command Prompt:

netsh advfirewall export "%userprofile%\Desktop\FirewallBackup.wfw"

Using PowerShell:

netsh advfirewall export "$Env:USERPROFILE\Desktop\FirewallBackup.wfw"

This command creates a backup file named "FirewallBackup.wfw" directly on your Desktop. Your firewall settings are saved into a single file for future use.

To Restore Your Settings:

Execute this command in either Command Prompt or PowerShell:

netsh advfirewall import "C:\Users\User\Desktop\FirewallBackup.wfw"

⚠️ Note: Remember to replace "C:\Users\User\Desktop\FirewallBackup.wfw" with the exact path to your backup file.

That completes the process.
