Update of Windows 21H1 with KB5001716 constantly fails with 0x80070643

Hi On my Lenovo X200 x64 based PC with windows10 21H1 windows update just flashes with KB5001716 and then gives error 0x80070643. No 3. Party AV, only defender. I have tried suggestions as described in Windows 10 Update KB5001716 Fails to Install - Solved and 10 Best Ways to Fix Windows Update Error 0x80070643 i.e. 1. Restart Windows Update Services 2. Reboot PC and Retry Update 3. Run Windows Update Troubleshooter 4. Run .NET Framework Repair Tool 5. Reset Windows Update 6. Perform a Clean Boot 7. Install Updates via Microsoft Update Catalog 8. Run an Anti-Malware Scan 9. Run SFC Scan or DISM Tool Any suggestions?



Solution: As suggested by Megahertz I made in-place upgrade and that solved the issue. I.e. PC upgraded to 22H2, still we don't know why upgrade from 21H1 failed.

Exactly the same issue started to happen several hours ago. I did first two options you've recommended but that didn't help. Don't want to perform a repair-upgrade though. There is definitely something wrong with this KB5001716.

P.S.

* First, there was an update which installed correctly, it's listed in Windows Update Log as "KB5001716, 2024-03"

* Immediately after that, when I checked for updates again, there is another KB5001716 which fails to install.

* Now, my Windows Update Log contains another failed entry for the same KB - "KB5001716, 2023-10" at the top (note that it has older date), with error code 0x80070643
