[German]It seems that the cumulative update KB4528760 installation problems are caused by the cumulative update KB4528760 released on January 2020 patchday for Windows 10 version 1909. Some users may notice a termination of the installation, reporting the error 0x800F081F.
A reader message
A reader of a German computer magazine has send me a feedback, , where a concerned person asks me, if I know anything about the error 0x800F081F in update KB4528760.
The last update of Win 10 last week always ended with the error message:
Failed… KB 4528760 – Fehler 0x800f081f
After that I tried the previously downloaded msu for KB 4528760.
After that I repaired it with dism.exe and svf and again with the update function and then with the msu.
The same error!
I still have the version of Win 10 pro 1909, Build 18363.418 on my computer.
I have also read about the update error in English forums. But without a solution.
The reader asks if this can be confirmed and if the error is an exception. I myself had my test machine updated last week with Windows 10 November 2019 Update (Version 1909), because I wanted to see if the Edge is offered as an update. There was no error displayed during the update installation.
Hits within the Web
However, it is by no means the case that there is only one individual concerned in the form of the above reader. I did a quick search on the Internet.
- In the German Microsoft Answers Forum there is this thread, where exactly this error is pointed out. I have followed the thread, there is no solution.
- In the Spanish speaking Microsoft Answers forum there is this thread, where you can find this error, but with Windows 10 V1903. Since both Windows 10 variants get the same update, this is not surprising.
- An English-speaking user describes the error code in connection with the update on reddit.com.
Currently I can’t give a solution, if foreign virus scanners are involved in this error is unclear.
What does the error code 0x800F081F mean?
Thanks to WaaS you would constantly have to extract some list of error codes for each build from the SDK to find out more about the error code. The error code 0x800F081F is therefore listed as unknown in the tools I use. However, I already mentioned the error code some time ago in the article Windows 10 V1903: Error 0x8024200D or 0x800F081F with update KB4512508.
The error code 0x800F081F stands for CBS_E_SOURCE_MISSING, i.e. the source files were not found. Some time ago I had discussed the error code in the German blog post Windows 10: dism-Reparatur erzeugt Fehler 0x800F081F. Furthermore, Microsoft has published a support article in connection with a .NET installation error. Microsoft provides the information that a file or folder, that is referenced by the update, cannot be found.
In such cases you will first try to repair the system or the component store (I mentioned this in the blog post Check and repair Windows system files and component store. Microsoft’s advice for Windows 10 users who have this problem is to use the Windows 10 installation media in question as the source for repair. Some advice can be found in this Microsoft article.
Fix: Try Inplace upgrade for repair
However, since most Windows 10 users don’t really get anywhere with these hints and the repair approaches described in the German article Windows 10: dism-Reparatur erzeugt Fehler 0x800F081F using sfc /scannow and dism don’t help. The only remaining repair is in Inplace Upgrade. This means: Lauch setup.exe of the appropriate Windows 10 installation medium from within a running Windows 10. This forces an installation of Windows 10 over the existing Windows, while data and programs are preserved. With this approach, however, missing features are installed subsequently, so that the update should be able to be installed afterwards. Maybe it helps.
