Hi,

I would like to get Windows Version (let's say 202H) and OS build (like 19042.928), as highlighted in below screenshot.
94332-image.png

Using Win32_OperatingSystem in VB.Net as ("root\CIMV2", "SELECT * FROM Win32_OperatingSystem")
And I am able to get partial build number 19042 using "BuildNumber" property of the Win32_OperatingSystem class ( win32-operatingsystem) However, I not able to figure out how to get:

  1. The remaining part of the build number (928 in this example).
  2. The Windows version like 20H2 (highlighted in green color in the screenshot).

    Hi @~OSD~ ,

    The Win32_OperatingSystem class can only retrieve the BuildNumber which is 19042 in your case, the last three (3) digits is the revision number of the build, to retrieve the revision number I believe you will have to query the Windows Registry.

    Will check that Leon.
    And how about the Version 20H2? Is it not supported as well?

    Great, I can get "DisplayVersion" now from Registry.
    However, in this hive, there is no such value like revisionID, I only have releaseID which is not same as last three numbers ....

    To get Windows version, you must get it from the registry.

    LabelVersion.text = My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion", "DisplayVersion", Nothing)

    For the Build : you need to put together the CurrentBuild and the SystemRoot like such

    LabelBuild.text = My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion", "CurrentBuild", Nothing) & "." & My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion", "UBR", Nothing)

    Enjoy!

    Pete
