Cumulative update KB5003214 fails to install

Iron Contributor

Hello Good afternoon Everybody ! Well unexpectedly ONCE AGAIN Windows cumulative update windows 10 version 21H1 build 19043.1023 failing to install after multiple attempts. This means this is the 4th update in last 3 months that causing severe headaches to Microsoft Users. Just 2 Weeks ago I moved front 20H2 to 21H1 and it went successful but then again the problem starting coming out of nowhere. Shout loud if you have been facing the same issue as I have been facing for quite sometimes now. Cheer Pals

Hello @Jauhar,


Can you share us the error code/message received while installing the update?

Also, try installing KB5003214 manually via Update Catalog, see if it works:


Hope this helps!




I would just add that this is an optional update - preview and should not be installed on all devices!

21H1 feature update by default does not require download of optional installations!



So this implementation is more complex!Zrzut ekranu 2021-05-28 174850.png

0x800f0922 is the error code. Nope dear Manual install wouldn't help either because MS updates works on a very simple theory. If it work then mood won't matter whether you update it automatically or manually. This is now quite a problem for the past few months
Hi dear ! I don't understand this language. Could you Please translate this message in English to know what exactly it says. Thanks



The screenshot shows confirmation that I installed kb5003214 properly, but this update will not install automatically in sleep - requires an open computer and power on!

Please do not enforce its implementation if your system language is not yet prepared 

by Microsoft!

Perhaps this is the cause of your problems with the latest Windows updates!





I agree with you that the download from Microsoft is unlikely to fail, and the preview of the update to 21H1 version is not available for manual download!


Installation to a stable version of 20H2 is also going well I'll add a screenshot that confirms it!Zrzut ekranu 2021-05-29 130751.jpg

No I have stopped more attempts to install KB5003214. I have delete everything from Software Distribution folder. Frankly no one has a solution for this nasty fail thing and MS is paying no attention not they're guiding us in order to walk away freely !



That is, you still have not installed the update preview?


BUSQUE ESTA INFO PARA VER SI ERA SOLO YO PERO VEO QUE HAY MAS PERSONAS CON EL MISMO PROBLEMA se reinicia desase los cambios por falla de actualización ya he echo y probado todo los métodos posibles la ultima opción que me va quedando es formatear y arrancar de cero pero seguiré esperando por si surge novedades sobre este fallo

I've also been having headaches running the updates the last few months.  Currrently with the 2021-05 Cumulative Update Preview for Windows 10 Version 21H1 for x64-based Systems (KB5003214), when running the update, I would receive the errors when installing that the computer is diagnosing problems and running repairs.  It then reboots and scaps the update gives me 0x80004005 for the error code. Currently running build 19043.899  and Windows Feature Experience Pack 120.2212.3740.0.  Tried doing the manual install and of course that was a no go.  @Jauhar 

Nope Not yet because it is not happening after multiple tries !
Hi Dear ! We I am running currently on build 19043.985 version 21H1. The greatest issue is that we haven't found any solution yet and nobody on this huge forum has any solution for the mess not even MS itself. You may visit my profile and a post of mine has been seen by 107K contributors but none of them has any idea about the solution. We all have tried all the available tips and tricks but all went in vain and the issue is still out there !



Try uninstalling unnecessary programs that run in the background and have the highest permissions, probably their operation prevents the closure of all processes to perform the migration of the new version!


I don,t have many apps installed. I keep my PC light always. All I have installed is iTunes and a couple of other Apps. MY PC has 600 GB or more space but I m not into unnecessary Apps and other media files


yes, but sometimes all you need is one application installed not in the Microsoft Store, which during the installation has obtained the highest privileges and its work is not compatible with the common environment


So you can not close its processes to install a new version of Windows preview - this causes the update to be rolled back!



It seems that the build you want to install is in the internal Beta channel distribution and the lack of a registered account prevents installation!

@Jauhar I have tried to upgrade Windows 10 using the media creation tool and it fix the same problem that you have mentioned. I have the same problem before installing KB5001330 and a lot of Cumulative Updates. Just select Upgrade This PC and make sure to select Keep Files and Apps to make sure that you still have the apps/files that you have before upgrading. For me, it takes about 1 hour from the Media Creation Tool up to a couple of restarts. But it depends on your internet speed. And now I can install all updates. Also tried SFC and DISM Scans but did not fix my problem.  Upgrading your PC will replace your Windows Files, but not affects Files, Apps, and Drivers. After that, there will be some updates in the Windows Updates after the upgrade.



Delete the ESD Folder in the C:/ directory

Settings/System/Storage/Temporary Files then scan our Temporary Files and delete the Previous Installation of Windows. (Deletes the Windows.old folder)


*Doing Optional things will make your drive space bigger as it deletes the files used in the upgrade, but its files will be needed if you have problems, to go back to the previous install/state.



Also, I tried it with my another PC, with an AMD A8 CPU that takes about 1 and a half hour for the upgrade process and it also fix the problem. Hope that works.
