Cumulative update won't install (KB4571756) (Error 0x800f081f)

I am running Windows 10 Home 2004 (Build 19041.450). Windows Update notified me that there was a cumulative update available to install (2020-09 Cumulative Update for Windows 10 Version 2004 for x64-based Systems (KB4571756)). When I told it to install the update, it will download and go up to "Installing - 100%" and then just show this error: 

I've tried the following in an attempt to fix the error:

  • Run "sfc /scannow" in an elevated command prompt
  • Run "DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:<Source of clean Windows 10 2004 ISO created using Windows Media Creation Tool> /LimitAccess" in an elevated command prompt
  • Uninstall and reinstall NET framework 3.5 from "Turn Windows features on or off" in Control Panel
  • Manually download the specific update from the Microsoft Update Catalog and install it
  • Stop the Windows Update service and delete the Windows Update cache located in "%SystemRoot%\SoftwareDistrubution", then restart the service

Obviously, none of these worked so I'm looking for any other solutions to this problem. Any help is appreciated.

    Looks like I've got everything on the list from the link you sent covered. Could it be device specific? Or is it just a buggy update?

    Hello  

    I am also facing exact same problem with Windows 10 update KB4566782 , KB4571756

    waited for September patch Tuesday but no luck stuck in update loop second time.

    I have tried all things all possible solutions to fix that problem  like you mentioned sfc, dism, troubleshooter manually installing update  but nothing works for me windows update always showed Error:

    0x800f081f

                                                  Method 1

     I haven't tried Resetting my pc You can if you want to give it a try

                                                    Method 2 (That resolved my issue)

    Then download the Media Creation Tool from Microsoft website and selected Upgrade this pc 

    to latest version from the list and keep all files settings apps 

    It reinstalled windows 10 and replaces all files But this process taken 4 hours for me 

    to complete depends on your PC specs and Internet connection 

    After reinstalling windows my sound driver stopped working then I checked windows update

    it installed latest sound drivers from my manufacturer and resolved that issue no problems in

    sound now

    It also installed September patch Tuesday without any errors

    I am  frustrated during the reinstallation process but all went smoothly for me uploaded the 

    screenshot after installing patch

    I thought Windows 10 update files get corrupted not all but some of them from time So it is showing error 

     Installing from ISO or repairing files won't worked for me 

    You have to reinstall windows 10 with Media Creation tool

    Or you can wait for Microsoft to resolve this issue with October patch

                                               Hope it helps

                                       Windows 10  version 2004

                                       OS version 19041.508 (after installing update)
