CBS registry key missing after failed update - Windows 2016 Server

I had a failed Windows update on a Windows 2016 Server. Now every time I run the Windows update it say there are no update.

After doing some research I found that a number of registry keys are missing from "Component Based Servicing". These are the keys available on the server at the moment.

Comparing this to another server which is working I can see the the keys ComponentDetect, Notifications, PackageDetect, UpdateDetect and Version are missing.

This explains why the server can not display and Roles or Features as well as not finding any updates.

I would like to add these reg keys by importing from a operational server which is at the same patch level and install software as this faulty one. Unfortunately it doesn't let me as I don't have the correct permissions. It will not even allow me to change the permission for the administrator.

Can anyone assist? I really don't want to rebuild the server which is a DC.

Thanks

    Sorry for the delay in getting back.
    So far I have had no success in fixing this problem. I believe it is to far gone and I may need to rebuild it. It looks as though the issue arose from a failed update; server restarted during update process while the updates were being applied. That is only part of the update process ran. Not a clever thing to do.

    I am in several minds as to ..

    1. Attempt to restore the server from a backup and allow it to resync with the other DC or
    2. Rebuild the server as @Anonymous suggested
    3. System Recovery from the console.

    Cheers
