    Hi to all posting,

    First please report the issue in the Feedback Hub

    using WIN+F so they get diagnostics.

    Also, are any of you using Windows Sandbox?

    If you are, disable it. I've read from some that

    that may be the issue.

    From what I’ve seen, it was said that this issue mostly occurs on systems with AMD processors; however, I also installed it on another laptop at home that has an Intel processor, and the same problem exists there too. https://youtu.be/mfUSxtWScQM?si=3QNqXDb9F3T-q_Ei

    What worked for me was to download the KB5132061 msu file -

    https://catalog.sf.dl.delivery.mp.microsoft.com/filestreamingservice/files/5775e69a-9a06-44b1-9b51-4bb89c81f212/public/windows11.0-kb5132061-x64_aedc878e9e078df2ec7e2cfb98dd5b21831cdbcc.msu

    Reboot the computer.

    Double click on the downloaded msu file to install the update.

    Olá todos !
    Estou com o mesmo problema

    (KB5132061) (26300.9974) Erro de instalação - 0x800f081f

    Já tentei fazer o download na versão 25h2 e agora na 26h2, fiz o procedimento de apagar as pastas Temp %Temp% Prefech e Recent ... apaguei a pasta SoftwareDistribution, e mesmo erro ocorre, ela baixa mas não instala. E tentei pelo catálogo e a mesma coisa está ocorrendo !

    Pelos relatos vejo muitos problemas semelhantes em várias máquinas.

    Será que teremos novas atualizações que corrijam ela ?

    If Windows remains responsive and the update is only showing “Installing” in Settings, restart normally and run the Windows Update troubleshooter; do not interrupt the PC if it is already displaying a full-screen update or restart phase.

    Microsoft currently lists no known installation-hang issue for KB5132061, so the absence of a published widespread issue means standard Windows Update recovery is the appropriate starting point—not that the cause is necessarily local. Build 26300.9974 corresponds to Windows 11 version 26H2. ^1^

    1. Restart and run the troubleshooter

    1. Save your work and select Start > Power > Restart.
    2. After signing back in, open: Settings > System > Troubleshoot > Other troubleshooters.
    3. Next to Windows Update, select Run.
    4. Restart when it finishes.
    5. Go to Settings > Windows Update > Check for updates. ^2^

    If the update is still stuck, continue below.

    2. Clear the downloaded update cache

    This removes downloaded update files, not installed updates.

    1. Press Win+R, enter services.msc, and press Enter.
    2. Right-click Windows Update, then select Stop.
    3. Open File Explorer and go to: C:\Windows\SoftwareDistribution
    4. Delete the contents of that folder.
    5. Return to Services, right-click Windows Update, and select Start.
    6. Restart the PC and check for updates again. ^3^

    3. Repair Windows servicing files

    Open Command Prompt as administrator and run these commands in order:

    DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow

    Wait for each command to finish. Restart, then retry Windows Update. Microsoft documents successful DISM completion as “The restore operation completed successfully” or “The operation completed successfully.” ^3^

    4. Verify the 26H2 prerequisites

    KB5132061 on Windows 11 26H2 requires:

    • An update released on or after September 22, 2026, such as KB5124010.
    • Servicing stack version 26100.9539 or later. ^1^

    To inspect the servicing stack, open Command Prompt as administrator and run:

    DISM /Online /Get-Packages | findstr /i "ServicingStack"

    The returned package identity must show version 26100.9539 or later.

    5. Install KB5132061 manually

    First open Settings > System > About and check System type. Download the Microsoft Update Catalog package matching the PC’s architecture—normally x64-based or Arm64-based—rather than assuming x64.

    If the Catalog download provides multiple .msu files, Microsoft specifies this order:

    1. windows11.0-kb5043080-x64_...msu
    2. windows11.0-kb5132061-x64_...msu

    Double-click them in that order. If the checkpoint update is already installed, Windows will report that it is already present. For an x64 package placed in C:\packages, Microsoft also documents this elevated command: ^1^

    DISM /Online /Add-Package /PackagePath:C:\packages\windows11.0-KB5132061-x64_.msu

    Use the actual downloaded filename. For Arm64, use the matching Catalog package and its filename; do not use the x64 package.

    If installation still fails, note the exact error code under Settings > Windows Update > Update history. That code is needed to distinguish servicing corruption, storage, driver, permission, and update-database failures.
