This article explains how to enable or disable all Windows Security notifications in Windows 11.
Windows puts notifications in Notification Center—right on the Taskbar—where you can get to them instantly. You can get notices in the Notification Center, including those from Windows Security.
In most cases, if you have a third-party or commercial virus and malware-preventing software installed, Windows will automatically disable its built-in Microsoft Defender Antivirus software and allow the third-party or commercial program to protect your Computer.
If you are still receiving Windows Security notifications even after installing third-party antivirus software, you can hide or unhide all messages from Windows Security.
Here’s how to do that in Windows Security for all users.
Enable or disable all notifications from Windows Security
As described above, Windows lets you hide or unhide all messages from Windows Security. If you don’t want to keep receiving information from Windows Security, here’s how to enable or disable this feature in Windows 11.
First, open the Local Group Policy Editor.
Then expand the following folders Computer Configuration > Administrative Templates > Windows Components > Windows Security > Notifications.
Computer Configuration > Administrative Templates > Windows Components > Windows Security > Notifications
Next, click on the Notifications folder on the left panel, and double-click the setting on the right called “Hide all notifications” to open.
When the setting window opens, select one of the options:
- Not Configured – Same as Disabled. Local users can see notifications from Windows Security
- Enabled – If enabled, local users will not see notifications from Windows Security.
- Disabled – If disabled, users local users will not see notifications from Windows Security.
Save your settings and restart your Computer for the changes to apply.
Enable or disable all Windows Security notifications via Windows Registry Editor
Yet another way to turn on or off all notifications from Windows Security in Windows is to use the Windows Registry Editor.
If you can’t open the Local Group Policy Editor, use the Windows Registry editor instead.
Open the Windows Registry, and navigate to the folder key paths below.
There are two locations.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender Security Center\Notifications HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender Security Center\Notifications
If you don’t see the Notifications folder key, right-click on the Windows Defender Security key, then create the subkey (Notifications) folders.
Right-click the Notifications folder key’s right pane and select New -> DWORD (32-bit) Value. Next, type a new key named DisableNotifications.
Double-click the new key item name (DisableNotifications) and make sure the Base option is Decimal, and then update the Value data:
- To disable all notifications. Type 1.
- To enable all notifications. Type 0.
You may also want to include the value name and data in the Policies key path: DisableEnhancedNotifications.
Save your changes and restart your Computer.
That should do it!
