Windows update (KB5034441) Error (0x80070643)

When I tried to install the windows update "2024-01 Security Update for Windows 10 Version 22H2 for x64-based Systems (KB5034441)" I received the error code (0x80070643).

I have already tried, restarting my computer, waiting a bit before retrying, running a memory diagnostic check, checking all my drivers for updates, installing optional updates, and running a malware scan.

When I tried to run the windows update troubleshooter it said "diagnosing problems" but never fixed them and I was still unable to install the update after running the trouble shooter.

Any help would be appreciated.

    I had the same error, read the responses in this thread and increased the size from 500 MB to 1400 MB, rebooted and the update went off without a hitch.

    Wish I could, or at least hide the bad update, but our system administration blocks both the wu troubleshooter and any partition changes (understandably). I'm in the ranks of those who wait...will it be days, weeks, months, years?

    The problem is that the suggested Microsoft workaround (involving a manual extension of the recovery partition using diskpart) may or may not work.

    I have a PC with dual Window 10 boot SSD's - I can boot Windows 10 from either SSD. One SSD has a recovery partition of 840Mb and KB5034441 installed OK, without the need for me to do a manual extension of the recovery partition. On the other SSD the recovery partition was only 460Mb and KB5034441 failed with the dreaded 0x80070643 error. I extended the recovery partition by 250Mb to 710Mb, using the Microsoft instructions. 0x80070643 still occurred. I tried extending the recovery partition again, this time to 960Mb. Same 0x80070643 error.

    I don't think that the recovery partition size is the only reason for KB5034441 installation failure - there must be some other potential cause, which is not addressed by the suggested Microsoft workaround.
