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

    The second solution worked but...

    disabled reagentc

    deleted 2 files with xml extensions in windows\system32\recovery

    ran WinUpdate and all previous failed updates including kb5048239 loaded to completion

    'Windows is up to date message.' History says so too.

    Restarted PC.

    ran reagentc /enable. Operation successful.

    Ran WinUpdate.

    Back to same issue. kb5042320 and kb5048239 try to run again, even though history says they ran successfully

    ???????

    have my fulldisk backup from earlier today to restore if necessary.

    Thanks to all that provided help.

    Here's my learning of how I finally got 'You're Up to Date'

    Hope this is not unique to me.

    My $WinREAgent directory in C had 3 folders: Backup, Rollback and Scratch

    Backup had boot.sdi, location.txt, ReAgent.xml and a winre.wim file (430,862 kb) I had extracted 6 months ago from a Win10 ISO dtd 5/5/23.

    Rollback was empty.

    Scratch had a file named update.wim (481,514 kb) and a folder named WimTempPath which was empty.

    Windows/system32/Recovery had 2 files

    ReAgent,xml and ReAgent_Merged.xml1

    So, I took the chance that 'update.wim' was really a winre.wim file that needed to be renamed and relocated.

    1. In Windows/system32/Recovery, DELETED both files above.
    2. Copy and pasted in update.wim
    3. Renamed 'update.wim' to 'winre.wim' with Admin privileges
    4. Ran Windows Update which failed.
    5. In a Command Prompt with Admin privileges, ran reagentc /disable command (success)
    6. Ran Windows Update which now succeeded. Takes longer than failed attempts took.
    7. Reboot computer. I saw instruction 'restart' but I first shut down followed by a physical ON button start and next did a restart by command.
    8. In a Command Prompt with Admin privileges, ran reagentc /enable command (success)

    Comment here: I would wait a bit between steps. MS seems to be doing a lot of reconfiguring at some points, creating new folders under $WinREAgent folder and then deleting them (or hiding them).

    1. Ran Windows Update which now succeeded under reagent enabled environment.

    I tried to perform your procedure, but in my case it didn't work.

    Simon -- that is not a lot of detail to be able to help you.

    Can you capture and post a screen-shot after every step?

    Also, please launch "Disk Management", and post a screenshot of that page.

    Updates KB5048239 and KB5042320 are installed, but when I restart the PC or click on check for updates it downloads and installs them again. The recovery partition is 1gb with 439.02 of free space.
