    How can I find out why Windows 10 2004 update fails


    Hi


    I'm unable to install Windows 10 2004 on my Lenovo Legion Y740-17ICHg laptop running Windows 10 1909 Pro and I'm wondering if there's a way to find out WHY it's failing to hopefully fix the problem.


    Windows update initially didn't offer the update, but a couple of months ago, it started offering the update. I told it to install the update three times, each time it got to 95% progress and then rolled back with an error code 0x8007042b. After the three failures, it stopped offering the update.


    I have subsequently used the Windows 10 Update Assistant multiple times, but it too fails in the same way.


    I do not have any 3rd party antivirus or security products installed just Windows Defender.


    I freed up over 50GB of disk space but this made no difference.


    I ran Windows Update Troubleshooter, again no difference.


    I followed the instructions here https://zcom.tech/windows-10-failed-to-install.html/ to:

    • Clear c:\Windows\SoftwareDistribution\Download
    • Run DISM restore health and sfc /scannow errors found and fixed according the console window but no affect

    I'm actually quite keen to install the 2009 update but this tries to install 2004 first.


    I'm not even sure what else to try.

    I'm a member of the Insider program and like to take advantage of the new features, although I've not yet installed any insider builds on this machine.

    :)

    When you finish testing the Avast suggestion, make sure that you restart your machine.

    Then if the issue persists, please return to the trouble shooting list in post# 89

    I think there are three steps that remain; the WU troubleshooter, reset WU components, and manual WU reset.

    How can I find out why Windows 10 2004 update fails

    Windows Updates failed to instal

    I'm not sure how differant XP media center Edition is but you could clear the history \ cache if these folders are there.

    Step 1 Register DLL files.

    =================

    By trying this step, we can check if the update engines are working properly.



    1. Close all instances of Internet Explorer.

    2. Click Start and Run, type "Regsvr32 atl.dll" (without quotes) in the Open box and click OK.



    Note: There is a space between regsvr32 and atl.dll



    3. Similarly, one by one, register the files listed below:



    Regsvr32 msxml3.dll

    Regsvr32 wuapi.dll

    Regsvr32 wuaueng.dll

    Regsvr32 wuaueng1.dll

    Regsvr32 wups2.dll

    Regsvr32 wucltui.dll

    Regsvr32 wups.dll

    Regsvr32 wuweb.dll

    Regsvr32 qmgr.dll

    Regsvr32 qmgrprxy.dll

    Regsvr32 jscript.dll



    Note: If you encounter errors while registering any of these files then skip that file and continue with the next one.



    If the issue persists, let's move on to the steps below to verify Windows Update services and temporary folders.



    Step 2 Verify the relevant Windows Update services.

    =========================================

    1. Click Start->Run, type "services.msc" (without quotation marks) in the open box and click OK.

    2. Double click the service "Automatic Updates".

    3. Click on the Log On tab, please ensure the option "Local System account" is selected and the option "Allow service to interact with desktop" is unchecked.

    4. Check if this service has been enabled on the listed Hardware Profile. If not, please click the Enable button to enable it.

    5. Click on the tab "General "; make sure the "Startup Type" is "Automatic" or "Manual". Then please click the button "Stop" under "Service Status" to stop the service.

    6. Then please click the button "Start" under "Service Status" to start the service.

    7. Please repeat the above steps with the other services:



    Background Intelligent Transfer Service

    Event Log

    Remote Procedure Call (RPC)



    Note: Event log service is enabled on all of the hardware profiles; this service does not have an option to enable or disable on certain hardware profile.



    If it still does not help, let's proceed to step 3.



    Step 3 Reload the Update temporary folders.

    ===================================

    One possible cause is that the temporary folder for Windows Update is containing corrupted files. Let's erase all the files there to get the system clean.



    1. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



    Net stop WuAuServ



    2. Click Start, Run, type: %windir% and press Enter.

    3. In the opened folder, rename the folder SoftwareDistribution to Sdold.

    4. Click Start, Run, type: cmd and press Enter. Please run the following command in the opened window.



    Net start WuAuServ



    Please test the Windows Update website and let me know the result. If the issue persists, to clarify the issue and provide more accurate troubleshooting steps, please assist me in collecting the following information.
