Win 10/11 - Disable Action Center

If you want to disable the Action Center you can do it with this -

Navigate to the following key:

HKCU\SOFTWARE\Policies\Microsoft\Wndows\Explorer

And create a new DWORD (32-bit) Value: DisableNotificationCenter with a value of 1.

You will need to either sign off and back on, or restart your machine for this to take effect.

You will also notice this is in HKCU (HKEY_CURRENT_USER) and as such is a per user setting.
