How to Enable or Disable All Windows Security Notifications in Windows 11
This guide shows you how to turn Windows Security notifications on or off for all users in Windows 10 and Windows 11.
Why would you do this? The Notifications page in Windows Security settings lets you control notifications. But it doesn’t cover everything. You won’t see critical alerts, like when virus protection turns off.
What happens when you disable all notifications? You’ll stop getting Windows Security alerts completely. This is helpful if you use a third-party antivirus program but keep getting notifications about Microsoft Defender being disabled.
Important: You need admin rights to make these changes.
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
