HI team,

System Type: x64-based PC

Processor(s): 4 Processor(s) Installed.

BIOS Version: Phoenix Technologies LTD 6.00, 11/12/2020

We can not update the 2025-10 Cumulative Update for Windows Server 2016 for x64-based Systems (KB5070882). Error code: 0X800f0922. Then we mount ISO source (we do not have the latest new ) and reinstall OS with the customer's application and configuration, but it still cannot be installed. We tried to manually install it using the following command. It doesn't work.

Command: net stop wuauserv; net stop bits net; stop cryptSvc; net stop msiserver;
ren C:\Windows\SoftwareDistribution SoftwareDistribution.old; ren C:\Windows\System32\catroot2 Catroot2.old; DISM /Online /Cleanup-Image /CheckHealtt; DISM /Online /Cleanup-Image /RestoreHealth; sfc /scannow

And we reinstall OS with the customer's application and configuration again. This time, We waited for the automatic update, but it lasted for 20 hours and got stuck in the download interface. As a result, we stop the automatic update. Simultaneously Windows Defender could not start.
Attached is the automatic update log :image (26).pngWindowsUpdate.log

Please help solve the problem. (Not considering a complete OS reload system as it may result in the loss of client application files)

    Hello Ping Guo,

    Thank you for the detailed information. The error code 0x800f0922 during installation of KB5070882 typically indicates a failure in the advanced installer phase, often caused by a corrupted scheduled task or IIS configuration issues.

    Here are recommended steps to resolve the issue:

    • Reset IIS configuration using wsusutil.exe usecustomwebsite false and verify that required IIS roles (e.g., ASP.NET, Static Content) are enabled.
    • Check CBS.log for entries related to Microsoft-OneCore-SecureBootEncodeUEFI-Task, which may indicate a failed scheduled task component.
    • Run DISM and SFC again, ensuring the ISO used matches the exact build version (14393).
    • Temporarily disable Windows Defender and retry the update, as Defender startup failure may be blocking update components.
    • If the update still fails, consider installing KB5070882 via offline servicing using DISM with the .msu file.

    If this resolves the issue, feel free to click “Accept Answer” so others can benefit too. Let me know if you’d like help reviewing CBS logs or preparing an offline update package.

    Best regards,

    QQ
