Hi, now Same issue with Lastest CU KB5000803 getting error 0x80073701
According to CBS Log it seems that package KB4499177 doing problems.
Package_3105_for_KB4499177~31bf3856ad364e35~amd64~~10.0.1.10.4499177-6706_neutral
I want to download it from the Update Catalog, unfortunately Didn't find it in Update Catalog, i think microsoft pull it off from there.
I did all possible fixes, maybe i missed something, i created a post before, With similar problem.
All possible fixes that i did there i comply here : [cannot-install-2021-02-cumulative-update-for-windo.html][1]
