  1. or better yet, use wushowhide.diagcab, WAU Manager, wumgr or windows update minitool to hide or block the offering of the KB5034441 update for Win10 21H2/22H2.

  2. MS consider to release those updated ISO files for Windows 10 2021 LTSC and 22H2, and even Windows 11 23H2 with the updates already slipstreamed in the Windows image and WinRE partition already adjust on 250 MB, especially if they want a fresh install.
