    Hi Pierre,

    If the normal update method is failing for the 26H2 update, try performing a quick update to 26H2 using this small enablement package from the Microsoft servers.
    https://catalog.sf.dl.delivery.mp.microsoft.com/filestreamingservice/files/94520a88-858f-4832-a57d-7211f6d84a4e/public/Windows11.0-KB5121794-x64_5e20a3cce48d6611b16bdec42b07167f5456586a.msu

    If that process also fails, click your Start Button, type winver and press Enter.

    Please provide a screenshot of the resulting dialog.

    Try this order:

    1. Go to Settings > Windows Update and select Check for Windows updates.
    2. Turn on Get the latest updates as soon as they’re available.
    3. If Windows 11, version 26H2 appears, select Download & install.

    If it still keeps failing, try these common fixes before attempting the upgrade again:

    1. Unplug nonessential hardware such as USB drives, printers, scanners, speakers, headphones, and external hard drives. If using a laptop dock, undock it.
    2. Install all current Windows updates first, including hardware driver updates.
    3. Uninstall non-Microsoft antivirus software temporarily, because it can cause upgrade problems.
    4. Uninstall nonessential or outdated software that might interfere with setup.
    5. Free up disk space so the upgrade has enough room to complete.

    If the device is eligible, Windows 11, version 26H2 is available for supported devices running Windows 11, versions 24H2 and 25H2. Microsoft also notes that safeguard holds can block the update on some devices if a known compatibility issue is detected.

    For immediate help with Windows Update issues, use the Get Help app in Windows or contact Microsoft Support.
