Note:
The compatibility appraiser task seems to be disabled on your system.
After editing the registry as mentioned earlier, please enable the compatibility appraiser using Task Scheduler. It's very essential for Windows Update.
Go to:
Task Scheduler Library > Microsoft > Windows > Application Experience.
Right-click on the Microsoft Compatibility Appraiser task and then select Enabled.
Right-click on the Microsoft Compatibility Appraiser task and then select Run. It takes a few minutes to complete.
After the task completes execution, restart Windows and check for updates. Let me know if WU offers 23H2 or 24H2.
