This tutorial will show you how to enable or disable Microsoft Defender Firewall notifications for all users in Windows 10 and Windows 11.

The Notifications page of Windows Security settings lets you configure what kind of notifications you want to receive.

The Firewall and network protection notification settings allow you to specify if you want to receive notifications when Microsoft Defender Firewall blocks a new app. You can also configure these notifications differently depending on if the app was blocked on your domain network, your private network, or the public network (internet).
