And now it started working again on the other machines...
Must be MS weekend.

Upgrade to Microsoft Edge to take advantage of the latest features, security updates, and technical support.
I created all 5 installation ISO files for all 5 Builds, but only 22557 contains all the system Apps required for a full clean install, the other 4 are missing all the basic Windows and System Apps needed for a functional system. Also, the App required for opening Windows Security (Microsoft.SecHeatlthUI) is missing, all this makes the resulting system unusable.
Last one on 22557.
Microsoft.SecHealthUI Microsoft.SecHealthUI_1000.22557.1.0_x64__8wekyb3d8bbwe
I noticed another issue common to all the Ni builds, if they are used for an upgrade or in-place they may only work correctly if they are done online allowing the check for updates.
If I use the option "Change how Setup download updates" to "Not right now", the upgrade or update in place still completes, but it creates a problem on subsequent W.U.
In this case W.U. goes in a loop trying to Download and Install the same Build over and over. Error 0xc1900401 is logged in that case.
I could not find a way out of that loop.
If I do the same upgrade or update in place online letting the Setup check for updates, as recommended, the process may complete correctly without subsequent W.U. loop issues, but the behavior is inconsistent depending on how the previous update was done.
The official MS Insider ISO 22579 includes all the required Apps and the Microsoft.SecHealthUI which is needed for opening Security.
