I don't know what is going on when I install latest updates for Windows 11 because it happened last time when I was trying to install 2025-10 Cumulative Update for Windows 11, version 25H2 for x64-based Systems (KB5070773) (26200.6901) and I am getting an Install error for 2025-11 Security Update (KB5068861) (26200.7171) today and I don't know why it is doing this. I tried going into Recovery and do Fix problem using Windows Update and that seem to work with the last update but nothing else seems to fix the update install error's. Here's the event ID from the Event Viewer: Installation Failure: Windows failed to install the following update with error 0x80070306: 2025-11 Security Update (KB5068861) (26200.7171).

Windows for home | Windows 11 | Windows update

    • Having had this update "... fail to install" roughly 6 or 7 times, despite ALL the suggestions and 'hacks' to supposedly 'fix' this, I will now just give up...
      I have work to do, and wasting my time making attempts to update or 'patch' this 'patch', is simply not getting me any further in what I need to do. Gotta figure that IF this is somehow (in some alternate reality) actually somehow "needed", then someone - somewhere - at Microsoft will manage to 'patch' this 'update' and POTENTIALLY it might get installed at some later time. But for now, I need to get back to my business and not spin my wheels with Microsoft's incessant updates.

    I resolved the issue by navigating to System > Recovery > Fix Problems Using Windows Update and clicking Reinstall now.

    Hi Jamie,

    Thanks for the exact error and build numbers. That is a generic servicing return that maps to system error 774 which simply means one or more errors occurred while processing the request, so it does not point to a single root cause. Given it is happening both with the October OOB (KB5070773) and today's November security update (KB5068861), the first fix is to repair the component store and then install the LCU offline using the Microsoft Update Catalog in the order Microsoft specifies for this KB.

    Open Windows Terminal as Administrator. First repair the servicing stack and system files. Run:

    DISM /Online /Cleanup-Image /RestoreHealth
    sfc /scannow
    

    When those finish, create a local folder such as C:\Packages. From the Microsoft Update Catalog, download the x64 packages for KB5068861 that the support article lists and place them together in C:\Packages. For this month Microsoft notes that this KB contains more than one MSU and that they must be installed in a specific order. If you want DISM to handle the order automatically, run:

    DISM /Online /Add-Package /PackagePath:C:\Packages
    

    If you prefer to install individually, install the prerequisite MSU first, then the KB5068861 MSU, for example:

    DISM /Online /Add-Package /PackagePath:C:\Packages\windows11.0-kb5043080-x64....msu
    DISM /Online /Add-Package /PackagePath:C:\Packages\windows11.0-kb5068861-x64....msu
    

    Reboot when prompted and then check Settings > Windows Update to confirm you are on OS build 26200.7171.

    For context about the error code, see Microsoft's System Error Codes reference.

    If anything in DISM or SFC reports it could not repair files, tell me the exact line so I can give you the next command. Otherwise, once you are on 26200.7171 you should be set.
