Hello, i search Windows Updates for integration:

Windows 10 21H2 > KB4023057 x86 + x64
Windows 11 > KB4023057 x64

Windows Update finds these updates, but I can't download them anywhere. Not even in the Microsoft Update Catalog

KB4023057: Update for Windows Update Service components

Release ChannelAvailableNext Step
Windows Update and Microsoft UpdateYesNone. This update will be downloaded and installed automatically from Windows Update.

It is also offered directly to Windows Update Client for some devices that have not installed the most recent updates.
Microsoft Update CatalogYesTo get the standalone package for this update, go to the Microsoft Update Catalog website.

Important The update that is available from the Microsoft Update Catalog applies only to all editions of Windows 10, version 1507, 1511, 1607, 1703, 1709, and 1803.
Windows Server Update Services (WSUS)NoSee the other options.

Note This update is currently not needed on devices that are administered through Windows Server Update Services.

I believe MS knows there's a problem integrating KB4023057 into current editions. Therefore, WU checks for eligibility.
If you look in Update Catalog, it's been re-released several times (not a good sign).
