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.

None of the steps in these threads have worked nor will work.The update is mainly X Box related and many of us just don't have that hooked up to their Win/10 system.Some of the updates ARE installed but other s are not and will not because of that.Unfortunately Microsoft has not created this update with the capacity to disappear after it has unloaded some of it's cargo.It is continuing to be a pest and hanging around seemingly for ever. One can only hope some bright light at M/S finally gets wise and finally fixes this glitch,sooner rather than later.

Add me, another one to this massive list of unsatisfied customers, cumulative have always been a problem on windows10, bring back windowsXP for gods sake, this os is a proper mess.

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
