Disable Windows Update from registry

I have a registry file that I have been using to disable Windows Update using the same keys that disable it in Group Policy, yet it is still not disabled. Checking for updates still happens but doing it at the user's request is not allowed.


These are the Group Policy settings that I use that completely disable Windows Update when done using Group Policy method:

Computer Configuration-->Administrative Templates-->Windows Components-->Windows Update-->
Remove access to use all Windows Update features, enabled
Do not connect to any Windows Update Internet locations, enabled

User Configuration-->Administrative Templates-->Windows Components-->Windows Update-->
Remove access to use all Windows Update features

Here is my registry file that has these same keys, yet it does not disable Windows Update, only disables being able to click the "check for updates" button or changing update settings in the Settings app.

HTML:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate]
"SetDisableUXWUAccess"=dword:00000001
"DoNotConnectToWindowsUpdateInternetLocations"=dword:00000001

[HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate\AU]
"NoAutoUpdate"=dword:00000001

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\WindowsUpdate]
"DisableWindowsUpdateAccess"=dword:00000001
"DisableWindowsUpdateAccessMode"=dword:00000000

Can someone please explain to me why my registry file does not work just like choosing the options in Group Policy???

 

this information is UNTRUE, as there is absolutely NO NEED for any third party tools or "hacks" to disable Windows Update or Windows Update from auto-updating.

using only the Group Policy keys listed above I have this configuration [see attached image--no auto-updating at all, no user is able to check for updates either, no updates ever], on the build 1803.

also, I do not have Windows Update Service disabled either, and still Windows Update is completely disabled.

This does not work, however, when only using the registry keys without going through Group Policy.

so again, can someone give me some actual help here???
