Every time 2025-10 Cumulative Update for Windows 11 Version 23H2 for x64-based Systems (KB5066793) tries to download to my computer, it fails. I have no idea how to correct. I did reach out a couple of weeks ago and all previous download failures were successfully updated.

    Hi, good day!

    Please let me know if you have tried the methods below.

    • Disable or uninstall any third-party VPN and Antivirus program to prevent it from interfering with the update.
    • Run the Windows Update Troubleshooter Open Settings > System > Troubleshoot > Other troubleshooters > Windows Update > Run troubleshooter
    • Make sure Windows Update and Background Intelligent Transfer services are available and running.

    Press Windows key+R to open Run then type: services.msc

    Press Enter to open Services app

    Double-click Background Intelligent Transfer Service.

    If the Startup status lists Stopped, click Start and then click OK. If the status is Running, right click then select Restart

    Double-click Windows Update.

    If the Startup status lists Stopped, click Start and then click OK. If the status is Running, right click then select Restart

    If the issue persists, open Settings > System > Recovery.

    Few things to check on the PC

    • Unplug all external peripherals except for the Mouse, Keyboard, and LAN cable before starting
    • Disable or uninstall any third-party Antivirus program to prevent it from interfering with the upgrade

    Under Fix problems using Windows Update, click Reinstall Now

    Once completed, your system will restart.

    I look forward to receiving your update and I'm willing to collaborate with you till we resolve the issue. Do keep me informed by clicking "Add comment" below.
