How to Turn On or Off Microsoft Defender Firewall in Windows 11

What is Microsoft Defender Firewall?

Microsoft Defender Firewall is a built-in security tool for Windows 11 that acts like a guard for your computer, stopping unwanted access from the internet or other networks.

• Domain network: Usually at work or school. Your device connects to a special system that controls access.
• Private network: Your home or a trusted network.
• Public network: Public 📶 Wi-Fi spots like cafes, airports, or hotels. Security needs to be higher here.

Keep the firewall on to stay safe. This is true even if you use other security programs.

Important: You need admin rights to change firewall settings.
