Micro$oft called it "Update Rollup".

Manual installation of patches and updates is still useful when you need
to reinstall your Win 10 in order to flush the system of junk.


I used WSUSOffline, to check out the offerings for Windows 10.

There is one big file per OS version, in the catalog.
In this example, as you noted in your subject line,
the 1GB update keeps being superseded by a later
1GB update. It appears the wsusscn2.cab file is not
updated with the last two supersedes.

You really only need to download a single 1GB file today,
to use for patching the OS. But be aware, that to attain
later updates, there will be an incremental download for
the purpose (as determined by the Delta Updater).

So yes, you can download a single 1GB file, but knowing
that it is never "the end of the update story".
