I know about that thread. But we are talking about updated packages, ie.: version 19044.3324 vs version 19041.1.
No longer necessary to bother with it manually. I have included it in Slimdown10 since version v1.60. I have tested it against updated Windows 10 Pro and it contains the same packages (same versions) like LTSC 2021 updated by the above Slimdown10 tool. Supported are all languages and both architectures (x86 and x64).
