On Windows 10, if you’re using the Microsoft Defender Firewall, the time will come when you may need to reset the settings to the default rules for a number of reasons, and this guide includes four ways to complete this task using Windows Security, Advanced Security (Control Panel), PowerShell, and Command Prompt.

The built-in firewall on Windows 10 includes a set of predefined inbound and outbound rules to allow or deny incoming or outgoing traffic to protect your computer from unauthorized access. However, you can always create custom rules and certain apps can also create additional rules to allow services to operate as expected, and over time, these rules can build up, and they can cause many issues.

The ability to reset the firewall settings can help to troubleshoot connectivity problems with apps or when setting up network file sharing. Or you want to clear a bunch of rules that are no longer needed, or you missed configure some rules and you’re not sure which one is causing the issue.

In this guide, you’ll learn four ways to reset the built-in firewall configuration to its default settings on Windows 10.

Warning: The steps below will remove all the settings you added to the firewall. If you have specific rules you want to restore at a later time, you can use these instructions to export the firewall settings. You can also use these instructions to backup and restore all the firewall settings on Windows 10.
