Windows 10: Cannot disable notifications in settings APP or group policy 1709

Installed 16299.15 RS3 on test machine.
Three notification settings cannot be disabled. Turn them off, and they just turn back on again.
(Notifications from Apps and other senders, notifications on lock screen and notifications about VOIP calls).
Turned them off, and went into group policy editor and disabled the notifications under user configuration. But of course that does not work because even though the slider moved to "Off" the settings are not actually being turned off.

Does anyone know of a fix?

Know the specific registry keys for these three settings? - If I set them off, assuming it's not Microsoft deliberately defaulting them to "ON" wouldn't that work?

thanks

Win 10 Toast Notifications Keep Reverting to Off

Without my turning them off, the Win 10 OS keeps turning of app notifications in the Action Center. In the notifications settings, a message is displayed that "Some settings are managed by your organization", even though this is a standalone computer,
not part of an organization (although on a home network). The "Show app notifications" toggle is set to off and grayed out. I can reverse this by using the Group Policy Editor to set the User Configuration/Administrative Templates/Start Menu and Taskbar/Notifications/Turn
of toast notifications setting to Disabled. However, after a while, the notifications turn off again and the notifications settings page looks like described above, even though the Group Policy Editor setting has not been changed. I can re-enable the
notifications for a while by setting the aforementioned Group Policy Editor setting to Not Configured and then back to Disabled but the notifications eventually turn off again by themselves. Does anyone know how to stop this annoying behavior and keep app
notifications turned on?

 

[Solution Found]"Some settings are managed by your organization" when trying to change notification settings.

Type "Edit Group Policy" into search and open the Local Group Policy Editor.

Navigate to User Configuration > Administrative Templates > Start Menu and Taskbar > Notifications > Disable "Turn off toast notifications" and you're done!
