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.

Hi,

The first step would be to try resetting Windows updates using an automatic script. See:

http://www.yourwindowsguide.com/2015/12/windows-update-complete-reset-in.html

Make sure you run the script as an administrator.


Try reinstalling manually then.

Hi,

I've had the same problem, but in addition to the op I downloaded the msu file to install, and it wouldn't install either.  It downloaded properly, and started installation then after a few minutes delivered the same message as the op had.  So maybe not a problem with windows update?

I did mention in my post that I downloaded the update from the Microsoft Update Catalog (the MSU that is). And no, it didn't work as mentioned before.

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)
