Error 0x80242017 when installing KB5004945 from WSUS (but not from Microsoft)
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.
- I posted a reply with the answer and it was removed. No idea why. It's a service stack update issue. If a computer missed the May cumulative update then KB5004945 won't install in my experience. The May CU included the latest SSU. Without it, you get 0x80242017
- It seems like there have been corrupted files on the system which has been fixed, did you manage to update after running the SFC command?
Are you able to install other updates?- Nope. Rebooted and retried after dism and sfc, and still failed with the exact same error.
- Are they Domain-Joined devices?
If yes, just for test try remove one of them from the Domain and see if the problem persist?
Make sure report this issue through the Feedback Hub app.
