Key notes
Don’t act surprised, as we were all expecting the first major update for Windows 11 to have some problems right at the start.
As you surely remember, last week, the Redmond tech giant releasedversion 22H2 for Windows 11, with a lot of new features and improvements.
However, right when users were trying to install this update, they were greeted byerror message 0x800f0806when the setup process failed time and time again.
Back then, Microsoft provided a temporary workaround, but there is no need for that anymore, as the tech company fixed the issue viaKB5019311(build 22621.525).
What is new with Windows 11 build 22621.525?
We are not looking at a long changelog for this cumulative update, as we got accustomed to, as this update was only designed for the installation issue.
Right after the release of version 22H2, when users were trying to do an in-place upgrade via Windows Update in Settings, the whole process would fail with error 0x800f0806.
Judging from early reports, manually downloading and installing the update seems to bypass this problem caused by trying to do an upgrade via Windows Update.
Another user affected by this Windows 11 installation error said that running the Windows 11 Installation Assistant also resolves the problem.
However, you don’t need to worry about this issue anymore, as Microsoft’s latest cumulative update is said to completely eliminate it.
Keep in mind that, since we aren’t talking aboutPatch Tuesday, this non-security update includes quality improvements only.
So, through this cumulative update, Microsoft addresses localization issues for some setup files, which might stop you from creating installation media for non-English languages.
Also, please keep in mind that, since it is an OOB update, it can be downloaded manually on Microsoft’sUpdate Catalogwebsite.
That being said, only install it in case you are facing issues with creating installation media for Windows 11 22H2 on non-English languages.
Needless to say, for other users that have nothing to do with the above-mentioned problem, this cumulative update is completely non-essential.
As a reminder, lately, we’ve also been looking atKB5017389(Release Preview Channel), andbuild 25206(Dev Channel).
And, since we’re talking about Windows 11 version 22H2, Microsoft also released a fix forNvidia graphics card errorsassociated with the new OS version.
Also, please note that the Windows 10 equivalent for this version, 22H2, is officially coming to all users in October,according to Microsoft.
What can I do if I can’t install KB5019311?
Also, make sure to report any other issues you might come across, in order for Microsoft to address and improve the overall OS experience for us all.
This is everything you can expect if you are a Windows Insider. Leave a comment below if you found any issues since installing this build.
