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.

My recommendation would be: If your ISP imposes data caps and you do not want to sit and download an ISO right now, wait for the next major update (20H2). If the September patch DOES NOT install, then the October patch DEFINETLY WON'T. If you don't have any data caps, download the media creation tool and perform an in-place upgrade (make sure the setup installs all the latest CUs that are available before beginning the in-place upgrade).

Welcome to the club, There was a similar issue in August with kb4566782, so I postponed updates until September patch Tuesday. When I restarted updates at that time kb4566782 was nowhere to see, KB4576478 installed ok but kb4571756 now failed in exact the same way as kb4566782. Meanwhile I learned about the Microsoft wushowhide tool to temporarily hide updates. When running windows update today I get the red text notice "Your device is missing important security and quality fixes" no kidding ! So hiding an update is equally useless as postponing updates. I surely hope Microsoft gets this mess fixed on October 13. No way I am considering clean, repair or update install. Linux is becoming more and more attractive.

I am suffering from the same problem on my new PC bought a week back. I've tried everything that was suggested through DISM in the following thread: https://answers.microsoft.com/en-us/windows/forum/windows\_10-update/windows-updates-is-stuck/dc20d165-c55a-431a-879a-56da9ebb4971 Please see the detailed response and logs which I have mentioned clearly in the above thread. Additional issue that I have is that "Pause Update for 7 days" and "Pause Until" (the drop-down for picking a future date in Advanced Options) is completely disabled. After thoroughly reading each and every message on this 14-page long thread, it seems that even the in-place repair may not be a sure way to fix. I also tried to install the Update for Windows (KB4577063) by directly downloading it from the MS Catalogue site, but its installation also failed. :-(( Please help me what to do next? Whether I should wait for the next release by Microsoft and till which date? Even if I do wait, will the new patch be installed because this one (kb4571756) might block its installation (??) Or, should I go for in-place repair? Thanks a lot

Using a downloaded ISO file should use much less bandwidth than repeatedly trying Windows Update: You only have to download the ISO once. You can use it like a Windows Upgrade, even if it is the same Winodws 10 version that you already have installed. Just mount the ISO file in Windows, which will create a new drive letter. Then run setup.exe from the new drive letter to repair or upgrade Windows. It preserves installed software and data files, just like upgrading via Windows Update. By default, this method will also add-in the latest Cumulative Update (unless you tell it not to). There should be a new CU available on October 13, 2020. You always have the option of backing everything up, creating USB bootable install media from the ISO file and then performing a clean install to a blank hard drive or SSD. But using an ISO file does not force you to do it that way.

My computer has tried running the update for a a couple of weeks now, and I still get the error as OP. I've tried all of the above, minus Installing from ISO. Id would prefer not to have to go that route as I don't have a constant connection to the internet and I don't like using bandwidth from my phone.

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

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.
