How to Enable or Disable All Windows Security Notifications in Windows 11
Disabling all Windows Security notifications in Windows 11 stops popup alerts from Microsoft Defender, including important warnings about virus protection and firewall status. This total block helps if you run a third-party antivirus program and want to stop duplicate or annoying warnings about Microsoft Defender being turned off.
You need administrator rights on your PC to change these notification settings. The standard Windows Security settings app only hides some alerts, so turning off all notifications requires a Registry Editor tweak.
You can disable all Windows Security notifications using the Local Group Policy Editor or Registry Editor. Navigate to Computer Configuration Administrative Templates Windows Components Windows Security Notifications in Group Policy, then double-click “Hide all notifications” and set it to Enabled.
Option 1Using Local Group Policy Editor
