Hi Emmanuel Santana,
To answer your questions:
1. Yes, the deployment was performed on a running system (not offline).
2. No, we did not use an offline image such as a mounted WIM.
3. No cleanup commands were executed after applying the update.
Currently, we've successfully deployed the September update [KB5065426] using the DISM method. The deployment completed without any errors, but the same three issues still persist.
And uninstall option is availble in control panel but uanble to uninstall it (screenshot attached below). [In previous thread, i mentioned as "The update installed via DISM does not provide an uninstall option in the Control Panel" instead of unable to uninstall the update]
For comparison, we tested the same DISM deployment method on a Windows 11 23H2 system. The update installed successfully, able to uninstalled the update without issue, and the registry retained information from the previous update. However, the update history was still not maintained.
Let me know if further details are needed.
