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.

    So I was having the same issue and solved it by doing an in-place upgrade with a USB drive created using the MediaCreationTool2004

    I had been reluctant to go that route because I was afraid to lose my data like with a reset, but in the end I gave it a shot and -hooray- this solved the issue for me. Took quite a while until everything was finished, also because of subsequently available updates, which had to be installed after the "big" update was done, but now my system is up to date. No more errors, and all my files and settings are still there.

    I have this same problem  myself  I had  done the media creation took process and every other process thats been listed to sort it. I also had the nvidia geforce gtx970 vga card device drivers completely erased from  the system from the windows repair tried to fix it.

    I got a Microsoft assistant to go through and try trouble shooting the system  via remote assistant.  I told him that the computer will not install or load up when i ran the update installation  multiple times. 

    He said he would try finding the issue why none of the original os drivers kept failing to install  after windows update  crashed  on install and completely wiped my  systems manufacturers files  . 

    After he remote assisted  and ran the 2004 install recovery  software  i had been told  to install  . And run  now had made bios issues now i can even boot up any hard of my harddrives to get back to windows at all.

    I now have lost a perfectly fine operating system  i use daily.... 

    Thanks alot Microsoft for completely destroying  my computer i had built for gaming.

    Yeah, I definitely agree.  MS rolls out these horrendous updates that can leave your PC inoperable for weeks or months.  I thought they said they wanted everyone on Windows 10 so that they wouldn't have these issues. It seems to me that every time they update, new problems are introduced. Sometimes with grave consequences, and they get away scotch free of any blame.  That's the Bill Gates formula for you.

    I have gone as far as to completely wipe my entire PC and reinstall windows and I am still having the same issues. **(KB4571756)**simply will not install, and I have tried every method suggested. The update tools fail and roll back all changes and I am now plagued with BSODs
