Followed the above steps except for in-place upgrade (since my PC does not have hardware to run windows 11). Problem persists.

Having same Issue with KB5034441 Update 01-09-2024 fails to install 0x80070643.

Totally agree with this comment.

I have same error when trying to update the same patch.

These are correct steps to take and have solved other update issues for me. However, there is another necessary step to try before resorting to the in-place upgrade, and that's clearing the update cache and forcing a fresh download of failing updates. Here is a link, scroll down to Seema-Bharti's post. how to clear windows update cache - Microsoft Community This has help me with other updates. However, none of these steps are helping today with KB5034441. From the system log: Installation Failure: Windows failed to install the following update with error 0x8024200B: 2024-01 Security Update for Windows 10 Version 22H2 for x64-based Systems (KB5034441). Keep in mind, if enough people are having trouble with an update, Microsoft usually supersedes it with a working update fairly quickly (that's the case where clearing cache and redownloading seems to be most helpful). I'll wait for a couple weeks before resorting to an upgrade in-place.
