Then click the Add button to allow the app through the firewall. The app is now allowed to bypass Windows Defender Firewall.

By all means Microsoft Defender Firewall should be enabled and receiving updates on your Windows computer. The only reasons you may want to turn it off is when you have other security products installed and Microsoft Defender is interfering with them.

If Microsoft Defender Firewall is not impacting your PC performance or interfering with other security suite installed, you should keep both installed and enabled.
