    I had same error when installing update KB5034441 which apparently the update have some issues. I found the solution from this forum https://answers.microsoft.com/en-us/windows/forum/all/update-kb5034441-fails-to-install/1b127728-67ce-4206-8978-b3b0e38044a8?rtAction=1705997118015

    The kb5034439 update is for servers. The update I get for my laptop which downloads but fails to install is kb5034441. Does this information apply to personal computers as well?

    I have read elsewhere, and now tried on several different computers, that a full re-install of Windows 10 from a fresh ISO download from Microsoft would fix this. It Does NOT.

    I service a lot of client computers which are stuck on windows 10, and they all end up with this error. Their computers still work so far. But the error concerns (sometimes frightens) them.

    Is this Microsoft's way of forcing people to buy new windows 11 systems?

    I truly wish that someone of Microsoft's systems experts would take this seriously.

    The error code 0x80070643 can be a pain when updating Windows machines. Here are a few additional things to try and hopefully get those updates installed:

    Double-check Windows Update Services: Make sure the Windows Update service, Background Intelligent Transfer Service (BITS), and Cryptographic Services are all running and set to automatic startup. You can check this by searching for "services.msc" and looking for those specific services.

    DISM Scan: Run a DISM scan to repair potential system image corruption. Open a command prompt as administrator and type: DISM /Online /Cleanup-Image /RestoreHealth (press Enter after typing). This might take some time.

    Run the Windows Update Troubleshooter: Microsoft provides a built-in troubleshooter that can diagnose and fix common update issues. Go to Settings > Update & Security > Troubleshoot and select "Windows Update" to run the troubleshooter.

    What is the solution for users that have no recovery partition?

    I received the update error every week with the last one on 02/21/2024, then no more attempts to install the fix. So for now it has stopped trying to install KB5034441.

    I have tried this on one of my computers to no avail. BUT, even if I can make it work, I support 20+ local computer users and this would be a time consuming nightmare.

    Surely Microsoft can spare a couple of their highly paid staff to resolve this.

    I had enough space already, but increased it by 500 MB anyway to 1.15 GB.

    The update still fails with the same error, 0x80070643.

    I'm still having the same 0x80070643 problem. Where there any updates made? Should i be waiting for Microsoft to fix it?

    Dear All,

    I have followed and implemented every single advice and rabbit hole possible. For some it worked, for me NOTHING WORKED. The time spent on fixing this issue from a user perspective is ridiculous.

    Here is what I suggest to SAVE SOME TIME.

    Create a back-up of your data.

    Download the latest OS 32 or 64bit on a 8GB or more usb storage device, using the windows tool. I am sure you are aware of this function. If not, google it.

    Here is the rub: Re-install Windows. When this happens, make sure you delete every single partition on your drive that you can get rid of.

    Resize the windows installation to take up less than what you have available on your drive.

    Then proceed.
