"After that you can update with W.U. again to 22621.232 and that should work too. I've done that several times."
I tried with two different machines and it never updates past 22621.105.
I have tried to pause updates and resume. It downloads the update again still won't update - just present the list again.
I guess I wait until next month's update or a new ISO show ups. I am not keen on installing a third-party ISO for security reasons.
I don't know what the difference is, I updated 3 machines to 22621.232 without any issues.
Just wait for next update, MS will hopefully fix the bugs. Plenty of users are having the same issue.
