[Solved] Windows 10 20H2 - New Registry Variable for Version-Number

OLLI_S · 22 Jun 2020, 20:12

In Windows 10 20H2 (Autumn 2020) you see a new text in vinver:

It is the text 20H2 in the version string.
In the current version you see: Version 1909 (Build 18363.900)

This is stored in the registry value DisplayVersion under HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion

Here the results from my PC (running 1909) :

@Tom I already had posted a topic for the version number in 20H2.

Tom · 18 Oct 2020, 14:42

As far as I can tell, then the official "name" will be 2009, rather than 20H2.
However, they didn't update the official pages with either name, yet.
For now we will stick with the name in the ReleaseId, as that seems to be the official one.

OLLI_S · 18 Oct 2020, 15:37

OK, we should watch the release of 20H2 and react....

OLLI_S · 19 Feb 2021, 07:45

Currently the version number 20H2 Build 19042.804 is shown, this number vontains 20H2.
@Tom So I assume this issue can be closed (or is there something left you have to do from your side)?

Tom · 19 Feb 2021, 09:45

@olli_s If you see the right result, then all should be good.

We added the "translation" of "2009" => "20H2" long time ago, and if it already says "20H2", then we leave it as is.

So I think it is safe to close this, else I am sure you will make a new post if you see other odd changes in Microsoft versioning

OLLI_S · 19 Feb 2021, 21:03

It is displayed the same way like in Windows.
So I close this issue.
@Tom Thank you for adding this,
