I use wuapi for scanning and installing updates on windows 10 computers. I find an update on my computer it gives details but i cannot find this update anywhere in windows catalog or even on wsus (I search in all classifications and products )
Title: Feature update to Windows 10, version 20H2 Classification: 3689bdc8-b205-4af4-8d4a-a63924c5e9d5 (Upgrade) KB: 5004237 Update ID: ff95561b-934d-4f58-af55-cabbdffb1a92
I cannot find this update on windows update catalog or wsus. This KB points Cumulative Update but wuapi gives me classification as Upgrade
The feature updates of Windows 10 are not available on Microsoft Update Catalog website for downloading. They can be deployed via patch management applications like WSUS, SCCM, etc. If you're looking at Microsoft Catalog Update website using your C# code, this is the probable reason why it doesn't list out the same.
If you've configured the
"Upgrade"classification on WSUS, then kindly perform a manual synchronisation. Hopefully, after a successful sync with Microsoft Update servers, all the feature updates (including v20H2) should reflect in the WSUS inventory.
