I have exactly the same problem as this (reported earlier this year), but with the new KB5048239 update. I get the 0x80070643 error when it tries to install. Retried several times, but same issue. I'm pretty sure this is the same problem that I had back in January, too. All security updates have worked fine since then, till now. At that time I was told that this was a general problem with the update and a fix was being made by Microsoft. I did wait and eventually that previous update went away. Now here we are again...

Hello,

The 2024-01 Security Update for Windows 10 Version 22H2 for x64-based Systems (KB5034441) will not install on my Windows 10 laptop computer.

I get the following message There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80070643) Retry

When I click on Retry it says its Installing-0% for a few minutes then Installed-100% and then I get Download Error (0x80070643) There were some problems installing updates, but we'll try again later. If you keep seeing this and want to search the web or contact support for information, this may help: (0x80070643) Retry

Windows Update Troubleshooter could not fix this problem.

I'm not sure what to do, please help.

Thank you

    Correct.

    Right-mouse-button click on the "CMD.EXE" file, and choose "run as Administrator", and try again.

    The presence of "C:\users\natal" instead of "C:\Windows..."

    indicates that you skipped that necessary step.
