The one updated with W.U. shows the correct level of SecHealthUI at 22581, the one that was updated with Home made ISO still shows the old one from 22579.
The machine that was updated with ISO also has the W.U. loop with the error we have seen previously 0Xc1900401, that even if the update/upgrade with ISO was done online letting it check for updates.
Luckily, I didn't get the loop (579 to 581 w/ 3rd party ISO & refused updates)
SecHealthUI same as yours
Lost TaskbarX again! 🤬
Lost Windows Background Spotlight as well, default picture only.
