Hi,
Just installed a clean copy of Win 10 Pro x64 v1709 and I cannot get the registry tweak to work:

Turn On or Off Notifications from Apps and Senders in Windows 10 Customization Tutorials

Settings > System > Notifications & Actions > Get notifications from apps & other senders...

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\PushNotifications]
"ToastEnabled"=dword:00000000

On a clean Windows install it does not work! Even after logout or restart. Please advise.
Cheers.
