@Duchemin, Dominique
Thank you for posting in Microsoft Q&A forum.
I am trying to see why the KB4562830 is missing from the Software Updates list...
Do you mean the update is missing from the "All Software Updates" in SCCM console?
It's normal, because this is a feature update for Windows 10, version 2004, all feature updates will go to "Windows 10 Servicing".
Any idea why it is missing from WSUS?
The updates in SCCM console are synced from WSUS, the update should lists in WSUS console, here is a screenshot of my WSUS:
What should I do to get the KB4562830 ? Or do I still need this KB shown as resolution of one issue on Windows 10 ? Has it been superseded? expired?
We can use it from "Windows 10 Servicing" as you are seeing. It has not been superseded by any update.
