I googled the actual KB and found this link: https://support.microsoft.com/en-gb/topic/kb5034441-windows-recovery-environment-update-for-windows-10-version-21h2-and-22h2-january-9-2024-62c04204-aaa5-4fee-a02a-2fdea17075a8. It seems that it updates the Windows Recovery (WinRE) environment, and the tip about resizing the partition for that is valid. You can find the link to the instructions in the KB article I linked.

I did that and the installation passed.

    As listed all over the comments, the solution is to extend the WinRE partition, which involves decreasing your OS partition. This does carry some risk and is a disaster to perform for +1,000 PCs.

    Anyway, some may find the output of the operation (cmd-line), when done successfully, to be useful and help eliminate any doubt about what to do with what partitions:

    I wasn't aware of the SoftwareDistribution folder, so thanks for the heads-up. But upon trying to install the Window update, I experienced the same failed result and error message after deleting the contents of the SoftwareDistribution folder.

    And yes, all relevant temp folders were also empty.

    In recent days I've experienced the same installation failure to which countless others in this thread have testified, including the "0x80070643" installation error message. According to my Windows Update History, my Windows 10 system successfully installed two "quality updates" on January 9:

    1. KB5034122 (OS Builds 19044.3930 and 19045.3930)
    2. KB5034275 Cumulative Update for .NET Framework 3.5, 4.8 and 4.8.1 for Windows 10 Version 22H2

    On January 10 and since, however, the system has failed to install the KB5034441 update.

    An additional complication in my experience is that there are other apps/updates that I can't install. Not every app! Not even most apps. But, for example, two 64-bit multimedia apps, both of which successfully launched the popup window that asked whether I gave permission for their installers to make changes to my system, but then produced nothing more than a couple of blinks of a yellow pointer arrow before stalling out and making no further progress with their installations. I've downloaded and installed other apps, both recently and today, so the issue isn't that I can't install *anything;* but the fact that I can't install apps in addition to the latest Windows update is curious and frustrating.

    The System Reserved partition is only 50 MBs. It needs to be at least 100 MBs but also needs around 60MBs free. Microsoft started using the small System Reserved partition in certain situations during an installation, but it might be you have a Legacy install which looks a little strange in a Windows 11 forum.

    I haven't looked at the instructions you are being given to repair the problem, but adding an additional 10 MBs to that partition will not fix this situation. You need to use a third party partition manager to make those changes.

    Perhaps converting the system to UEFI might help, which you need to do anyway. That would add a 100 MB System UEFI partition.
