A number of environments need to disable the Notification Center and Action Center features in Windows 10. This can be done using the registry editor or using a Group Policy Object (GPO).
First let’s look at doing so with the registry. As with any mucking around with the registry, when editing, I strongly recommend backing up the registry and/or creating a restore point first. Once done, click Run, enter regedit and hit Enter to open the Registry Editor.
Next, right-click on the HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Explorer registry key and create a new DWORD (32-bit) key. Call the key DisableNotificationCenter and provide the number 1 as the value. Then quit the Registry Editor and restart. Notification Center and Action Center should then be disabled. Simply delete that key and reboot in order to go back.
If the Group Policy Editor is available, click Run and enter gpedit.msc. Then open the User Configuration, navigate to Administrative Templates, click on Start Menu and then choose Taskbar. Open Remove Notifications and Action Center, and move the Enabled option to Disable (if disabling of course). You can then run gpupdate or reboot to see the change.
