[SOLVED] Windows 10 (LTSC) fails to install cumulative updates

[AimarPL]

Hi there! :)

I'm having a W10 installation that fails to install cumulative updates (from wsus / manually downloaded). Each time it's getting downloaded, installed, the system reboots, and... rolls back.

SFC / DISM finds no errors; sfcfix didn't find any issues too, yet.... system cannot install these updates properly

I'm attaching CBS logs, perhaps someone can help me out with fails that are listed there.

Thank you for any possible hints here :)

ok, I have found an issue;
app-readiness service was depending on citrix app layering service which was causing it not to start when required for windows updates that needed a reboot.

after removing citrix services windows update worked like a charm.
