Windows 10 - Disable warning notification about disabled firewall via GPO

Solution 1:

  1. Click the Start button, type Security & Maintenance and then click on the Security & Maintenance control panel option. You can also go directly to the control panel and get there that way.

  2. Choose Change Security and Maintenance settings.

  3. Uncheck Network Firewall

Solution 2:

It's not possible to disable the firewall notifications alone, but since Windows 10 build 1607 it has been possible to disable all Security and Maintenance Notifications using

HKCU\SOFTWARE\Microsoft\Windows\CurrentVersion\Notifications\Settings\
Windows.SystemToast.SecurityAndMaintenance\Enabled = 0 (DWORD)

UPDATE: According to Ladislav Louka, the required value has changed to 1 since build 1809.

Either add this registry key directly via Group Policy or create a custom ADMX template for it. See Disabling Windows 10 Notifications via Group Policy by Jeffrey Harness.

I think any of these notifications equally doesn't need attention of a single user, but these settings must be monitored & maintained by the administrators, instead. The scope of this modification seems ok.


Solution 3:

I have spent 3 days testing this on 2 machines. When the following is in place the notifications do not pop up for the the firewall. When I remove them they comeback. I also tested inserting this into the default user hive so that all new users logging in will get the the registry change.

This is for Windows 10 1809.

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\CurrentVersion\PushNotifications]
"NoToastApplicationNotification"=dword:00000001
"NoToastApplicationNotificationOnLockScreen"=dword:00000001

Solution 4:

Computer Configuration -> Administrative Templates -> Windows Components -> Windows Defender Security Center -> Notifications -> Hide all notifications
