    Windows 10 May 2020 Update Failing - MCT Stuck at 31%, Update Assistant 99%


    Trying to manually update to Win10 May 2020 - 2004 build.


    Currently at 1909, regular 'Check for updates' does not detect anything needed.


    Looking at the update log Get-WindowsUpdateLog - it always ends with

    > 2020/06/12 11:35:33.8074436 14224 9372 Shared * END * Service exit Exit code = 0x240001


    Yet the updater will remain open for hours with no progress.


    Media Creation Tool gets stuck at 31%

    Update Assistant at 99%


    I've run

    DISM.exe /Online /Cleanup-image /Restorehealth

    sfc /scannow


    After rebooting when they got stuck.


    Also attempted the ResetWUEng suggested -

    Ran through -

    2. Resets the Windows Update Components.

    3. Deletes the temporary files in Windows.

    :)

    Windows update assistant stuck at 99%

    This is what I see, and have seen since 7 am it is now almost 11 am.
    I already had 10, just needed the updated version.
    I said that about my wifi because microsoft keeps telling people to use a wired connection.
