Windows update failed to download but not all patches

Question

Hello All,

I am facing issue with patch deployment. We have deployed 3 patches for Win10, one patches installed successfully but other 2 SSU and CU downloading failed at 13 %.

In Wuahandler.log it’s showing “0xca00a004”  how we can start troubleshot, it’s seems like not related to configuration.LogSS - How To Manage Devices Community Forum - Welcome to the world of Device Management!

  1. Just to check… how is the communication like is there a network latency and content availability ?

  2. Yes SSU update failed to download Joymalya Basu Roy% with the error code 0xca00a004.
    I don’t understand why?
    In error lookup didn’t find anything

    • * download failed 13%.

      • I don’t think anyone can help without checking the log files…

        The flows which you need to check things from client side
        1. Locationservices.log – Check whether it’s able to find WSUS Path= and Distribution Point with patches
        2. WUAHandler.log to check whether scan is completed or not
        3. Updatedeployment.log – Check for deadline of the assignment and Software Updates client configuration policy, DetectJob completion received for assignment, Added update (Site_, PercentComplete, etc…
        4. Execmgr.log – Execution is complete for program Software Updates Program
        5. RebootCoordinator.log – Reboot related things

  3. HI,

    Generally SSU updates install first on machines then only it will allow to install security updates.

    From your screenshot sSU update failed.

    Thanks
