    2020-11 Cumulative Update for Windows 10 Version 2004 for x64 based Systems KB4586781


    I am told "Your device is missing important security and quality fixes.". Apparently these are contained in the subject update.


    I have tried to install the update for several days and repeatedly get the message, "Failed to install on date this- 0x80073701."


    The update downloaded satisfactorily but then the install fails at some point. This is varies between 14% and tonight even 100% was stated to be complete, but followed by a failure message.


    I have searched the web and tried every procedure suggested to install this allegedly vital update. Because I cannot install this update I am unable to download and install the Feature update to Windows 10, version 20H2.


    Am I now stuck with a PC that cannot be upgraded in future due to this stubborn update not installing.


    I would be most grateful for advice from those who have successfully overcome this hurdle, as tohow I should proceed.


    John

    oh no, I hope mine won't go BSOD soon! Keep failing 3 times already for this Windows Update, It tried to rollback the update & luckily my desktop is still able to boot up.

    My machine is totally useless after this KB4586781 update. Machine was fine up until Thursday 11/12. Windows Applied patch overnight. Woke up to machine at the recovery screen and has been in a perpetual Attempting Auto Recovery/Diagnosing PC loop since.
    None of the recovery tools - Startup repair, uninstall last quality update, restore point worked. System did have a pending.xml file remaining in the c:\windows\winsxs directory in it, and hw diagnostics and chkdsk /r all checked out fine. The last 4 entries
    in the WindowsUpdate log included:
    Success Content Install Installation Started: Windows has started installing the following update: 2020-11 Cumulative Update for Windows 10 Version 2004 for x64-based Systems (KB4586781)
    Success Content Install Installation pending
    Success Software Synchronization. Windows Update client detected 1 update
    Success Software Synchronization. Windows Update client detected 9 updates
    This is brutal. Anyone else seeing any failures like this? Any suggestions (before what looks like the inevitable and totally unacceptable reinstall)?
