Privacy and Security Reset Microsoft Defender Firewall Settings to Default in Windows 11

This tutorial will show you how to reset Microsoft Defender Firewall settings and rules back to default in Windows 10 and Windows 11.

Microsoft Defender Firewall in Windows helps safeguard your device by filtering network traffic and blocking unauthorized access. It reduces the risk of network security threats by restricting or allowing traffic based on various properties such as IP addresses, ports, or program paths.

If someone, or something, has made changes to your Windows Firewall settings that is causing things not to work properly you can reset the settings back to the way they were when you first got the computer. If you are joined to a work or school organization that has applied any policies to configure the firewall, those will be reapplied.
