I have several clients running Win 10 v20H2 that are failing to install the update "2021-07 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB5004945) from our WSUS server with "Status: download error - 0x80242017". However, if I manually log into the workstation and "Check online for updates from Microsoft Update", it downloads and installs the update with no errors.
The "Self Contained" cab file for the update is present in the proper directory on the WSUS server, although the two "Express" files are not. The WSUS server is running on Windows Server 2019 v1809.
Here's what I've done for troubleshooting on the client side:
Run Windows Update Troubleshooter: It can't find any issues.
Reset Windows Updates components "manually" using batch script.
Run dism /online /cleanup-image /restorehealth
Run sfc /scannow
I've attached the System and WindowsUpdateClient event logs, as well as the CBS.log and DISM.log from the workstation I'm troubleshooting with.

@skilley1425 That did it.
It looks like the issue was happening on newly imaged machines with a base install of 20H2, so when Windows Update tried to skip straight to the 2021-07 CU (KB5004945), it didn't have the servicing stack update from the 2021-05 CU (KB5003173).
I download "2021-05 Cumulative Update for Windows 10 Version 20H2 for x64-based Systems (KB5003173)" from the Windows Update Catalog and manually installed it and rebooted, and after that, KB5004945 downloaded and installed from WSUS with no further errors.
I'd say MS needs to mark KB5003173 as a prereq for installation of KB5004945.

@skilley1425I have just tested this solution and have installed the KB5003173. Even after a reboot, I continue to get into the error. Are there any other ideas or do I need to do something else? I am clueless

@skilley1425I have installed KB5003173, and KB5004945 still fails to install. Or more correctly, it installs but on reboot, it fails to complete and has to roll back. The new KB5004237 fails in the same fashion. It seems there is some component that is checked at restart that is failing and a rollback is triggered. All I can do is clear the Software Distribution folders and pause the updates or else I am bugged with a rollback attempt every time I start my PC.

@arossi1512. did you ever make any progress with this issue? we're battling the exact same thing here.....i thought i was making some headway by first manually installing kb5005260 and then kb5003214 , reboot and then 5004237 would install fine but found that doesnt work in all cases and even then the latest 5005033 from august fails at the same 98% post install reboot stage (and takes a good 20-30 min at that stage to undo the changes). this is getting pretty old ! in our case we were either on 2004 or 1909 and did a 20h2 upgrade w/ the /dynamicupdates set to disabled (to save time and just let wsus handle the updates after like usual) so not sure if that has anything to do w/ this or if microsoft just botched more updates on us here
