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.

    I'd be happy to ignore the update. The problem is that Microsoft Update will not let it go. It insists I need to update whether I'm shutting down or restarting. So there's that...

    Hi,

    I suggest pausing the updates for 7 days and keep an eye on this thread for the new update.

    I paused updates for a month, and looks like I have to do it another month. I get the same error no matter how many times or steps I try in all the WU reset tutorials. I'm currently running off of the latest ISO, and did a clean install just this year because a cumulative update from 2019 wouldn't install on my last install.

    Windows 10 is single-handedly the WORST and most constant update experience I've had in my life, and I've been maintaining computers since Windows 95. This OS as a service thing is hot garbage. Over a %75 failure rate on cumulative update packages. I absolutely hate this )*($.

    Everyone, try with this command:

    DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:X:\sources\sxs

    If you want to be more specific follow the steps on this video

    If I achieve anything I'll post back

    Didn't work for me. I followed all the steps, but the update still won't install with the same error code 0x800f081f.
