i have the same issue and absolutely none of the random guesses from microsoft on this thread have worked.
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.

2020-09-20T21:22:19+00:00 Ive been trying for over a week to install this update KB4571756, the same thing keeps happening, the update downloads fine, it's gets up to 20% when installing, then goes to 44% then straight to 100% and then the error code of 0x80073701 comes up, i even installed Reimage PC Repair which Windows recommended would fix the problem, it didn't and cost me £31, bloody con!! from the comments on here this is widespread, so can one of the so called experts on here come up with a solution for this problem for everyone and preferably an easy to fix solution, we're not all tech bloody savvy!!

2020-09-21T06:31:07+00:00 So Microsoft is addressing the issues with September patch
https://www.windowslatest.com/2020/09/15/windows-10-september-2020-update-issues/
Hope October patch resolves these issues and not come with its own new issues
My issue get resolved
By using Media Creation Tool
and Upgrading my pc
I also haven't experienced any issues till the installation of September patch

2020-09-21T07:50:31+00:00 Yeah the in-place upgrade using the media creation tool is a 50/50 chance. It works for some and doesn't for others. It's no perfect fix, and I couldn't resolve it by doing that either.
