Windows 10 V1909: Strange Update Status …. Bits jammed?

[German]Just a brief information about a crude behavior of Windows 10 November 2019 update. Just got a case under my eyes, where someone allegedly got the version 1909 without approval for the installation of the feature update. But it's not that easy, it looks to me as if bits are jammed.


Strictly speaking, it looks to me as if the software plumbers from Redmond don't really get their bits & bytes sorted out in a proper manner anymore.

Windows 10 V1903 and V1909 share the same code

I've discussed it within my blog post Windows 10 V1909 released, how to get this update? Microsoft had the idea to provide the same updates for Windows 10 Version 1903 (May 2019 Update) and Windows 10 Version 1909 (November 2019 Update). Those who already work with Windows 10 Version 1903 will have the code for Version 1909 already on their hard disk. The distinction between the two Windows 10 versions is made only by the build number.

  • Windows 10 Version 1903 uses Build Number
  • Windows 10 Version 1909 uses Build Number

To upgrade from Windows 10 Version 1903 to Windows 10 Version 1909 you need an Enabler Update (KB4517245). This unlocks the relevant features for the Windows 10 November 2019 update and changes the build number from 18362 to 18363.

Funktionsupdate für Windows 10, Version 1909

The enabler update KB4517245 is offered to users in Windows Update as a feature update to Windows 10 Version 1909. The download and installation must be initiated explicitly via Download Now and Install link. 


A crude case: Windows 10 V1909 without approval

At I became aware of a crude case. Tero Alhonen hat documented it at Twitter with screenshots (see below).

Tero Alhonen says that although he is a Seeker (he had searched in Windows Update), he never agreed [to Download and install now] to install the feature update. Nevertheless, he was suddenly offered a reboot to install the feature update on Windows 10 Version 1909 on the Windows Update page (top screenshot in the tweet above).

But it gets even crazier, as the screenshots in the lower tweet show. The update history page indicates a successful installation of a Feature Update to Windows 10 Version 1909 on November 21, 2019 on that machine. . But it gets weird when you look at the version value shown in the screenshot. Winver reports build 18362.418, which is Windows 10 version 1903 according to my explanations above.

So what Tero Alhonen has on his system is somehow not Windows 10 Version 1903, but also not Windows 10 Version 1909. It seems that some bits are jammed pretty well. Or it's a big joke from Tero – who knows.
