How to Enable or Disable All Windows Security Notifications in Windows 11
Blocking all Windows Security notifications in Windows 11 stops popup alerts from Microsoft Defender, including warnings about virus protection and firewall status. This total block helps if you run a third-party antivirus program and want to stop duplicate warnings.
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 (a tool for changing advanced system settings) 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
Local Group Policy Editor lets you manage Windows Security notifications through system settings if you use Windows Pro, Enterprise, or Education editions. You can open the policy tool and change settings in the Windows Security folder to turn alerts on or off. This built-in tool changes how Windows handles security warnings without editing the registry directly.
- Open the Local Group Policy Editor. Type
gpedit.mscin your search bar and press Enter. - In the left pane, navigate to this location:
Computer Configuration > Administrative Templates > Windows Components > Windows Security > Notifications - Look at the right pane. Double-click on Hide all notifications to edit it.
- To enable (turn on) all notifications:
- Select the dot next to Not Configured
- Click OK
- To disable (turn off) all notifications:
- Select the dot next to Enabled
- Click OK
- Close the Local Group Policy Editor.
Option 2Using Registry with Commands
Registry commands let you control Windows Security notifications on any version of Windows 10 or 11, including Home editions where policy tools are missing. You run administrative commands in Windows Terminal to update system registry keys and turn all security alerts on or off at once. This method works fast if you prefer typing commands instead of clicking through menus.
Right-click on Windows Terminal and choose Run as administrator
To enable (turn on) all notifications: Copy and paste this command:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender Security Center\Notifications]
"DisableNotifications"=-
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender Security Center\Notifications]
"DisableNotifications"=-
[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender Security Center\Notifications]
"DisableEnhancedNotifications"=-
To disable (turn off) all notifications: Copy and paste this command:
reg delete "HKLM\SOFTWARE\Microsoft\Windows Defender Security Center\Notifications" /v DisableNotifications /f
reg add "HKLM\SOFTWARE\Policies\Microsoft\Windows Defender Security Center\Notifications" /v DisableNotifications /t REG_DWORD /d 1 /f
Press Enter and wait for the command to finish.
Summary
Controlling Windows Security notifications depends on your edition of Windows and whether you prefer using policy settings or command lines. You can use the Local Group Policy Editor on Pro editions or Registry commands on Home editions to turn alerts off. Stopping these alerts helps prevent pop-ups when you run another antivirus program on your computer.
