Update with Windows Update (issue)

Hello everyone,

I am facing an issue with the update via WINDOWS UPDATE that is not fully downloading the patch from June 9, 2026 – KB5094126 (operating system builds 26200.8655 and 26100.8655).

I am on Windows 11 Pro version 25H2.

Initially, I was told to clear the cache, which has been done, but without results.

Then I contacted the Microsoft platform, which took control of my PC to reinstall Windows 11.

Apparently, according to them, this would solve the problem, but no.

I don't know what to do for this notorious update, which seems to be important.

What do you think?

Thank you in advance for your feedback.

Pierre.

    Hello,

    You are clearly not an isolated case with this type of cumulative update that gets stuck... and the fact that even a reinstallation hasn’t changed anything gives an important clue: the problem is probably deeper than just the Windows Update cache.

    Before going any further:

    Do you have an error code?
    (e.g., 0x800f081f, 0x80070002, etc.)

    If yes, please give it to me → it helps to directly pinpoint the cause.

    Re,

    First of all:

    My honest opinion

    This update is important (security + stability)
    BUT if your PC is working perfectly:

    you can wait for the next cumulative update (they replace the old ones)


    - First solution:

    Repair Windows thoroughly (DISM + SFC)

    Even after reinstallation, it can still be corrupted.

    Open Command Prompt as admin and run:

    DISM /Online /Cleanup-Image /RestoreHealth

    (wait for it to finish → sometimes long)

    Then:

    sfc /scannow


    Second solution:

    Complete Windows Update reset (cleaner than simple cache)

    In the admin prompt:

    net stop wuauserv
    net stop bits
    net stop cryptsvc
    net stop msiserver

    Then:

    ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
    ren C:\Windows\System32\catroot2 catroot2.old

    Then restart:

    net start wuauserv
    net start bits
    net start cryptsvc
    net start msiserver

    Then restart the PC

    Third solution:

    Manually install the update (often a drastic solution)

    Go to the Microsoft Update catalog:

    https://www.catalog.update.microsoft.com/

    Search for:

    KB5094126

    Download the version corresponding to:

    Windows 11 25H2
    x64

    Run the .msu file

    If it fails here too → system issue confirmed

    Lastly:

    Update your BIOS

      Good evening Bruno and thank you for your help.

      I tried the first solution, which gave me the message "Error: 740.

      Elevated privileges are required to run DISM.

      Please use a command prompt with elevated privileges to perform these tasks."

      For the second solution, how do I access the admin prompt?

      Sorry, but I'm not very good with computers at all...

      If the first two suggestions don't work, I might get back to you for the third one.

      In the meantime, I wish you a good evening.

      Pierre.

      Good evening Bruno,

      I have implemented all the solutions you provided, but the only updates available to me are for Microsoft Defender Antivirus.

      However, the one I am interested in (KB5094126) is not showing up.

      So, I won't go any further, and maybe one day it will show up.

      In any case, thank you for your help.

      Pierre
