Hi Rodney,
Thank you for posting here.
If you need to query the list of updates approved by WSUS, I recommend using the [Computer Tabular Status for Approved Update] report in WSUS console.
If you need to query the list of updates that the client has installed, it is recommended that you query it directly on the client by referring to the method mentioned in the article: "Windows:
How to List All of the Windows and Software Updates Applied to a Computer".
Hope the above can help you.
Regards,
Yic
