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.

Did you try the Update now button also? https://www.microsoft.com/en-us/software-download/windows10 It might not incorporate the October 1 Cumulative Update until next week. I found today's CU on my wife's PC listed under Optional Updates on the Windows Update page in Settings.

I tried everything listed in this e-mail and none of it worked sadly! I guess this is the end of the road for installing patches on this windows 10!

Used to it by now. Not the first time either.

Cumulative update won't install (KB4571756) (Error 0x800f081f)

Anonymous

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.
