Environment.OSVersion in PowerShell vs PowerShell ISE

Question

Why is it that I see 2 different versions of my OS from PowerShell and PowerShell ISE?

The OS: Microsoft Windows Server 2012 R2 Datacenter Evaluation

PowerShell: version 4.0

PowerShell

PS C:\> [System.Environment]::OSVersion.Version

Major  Minor  Build  Revision
-----  -----  -----  --------
6      3      9600   0

PowerShell ISE

PS C:\> [System.Environment]::OSVersion.Version

Major  Minor  Build  Revision
-----  -----  -----  --------
6      2      9200   0

In Windows 8.1 / Server 2012 the GetVersionEx return the data for Windows 8 (6.2 Build 9200) if the application doesn't contain the supportedOS Id for Windows 8.1.

Looks like the GUI doesn't include this entry.

@Kiquenet yes, 2012 = 6.2 and 2012R2 = 6.3 – magicandre1981 Jan 08 '15 at 17:13
How difference **Windows Server 2012 and Windows 8** and How difference **Windows Server 2012 R2 and Windows 8.1** ? – Kiquenet Jan 08 '15 at 21:03
@Kiquenet which programming language do you use? – magicandre1981 Jan 09 '15 at 05:33
C# .NET and Powershell – Kiquenet Jan 09 '15 at 07:01
@Kiquenet make sure that the supportedOS Id entry is added to the app.config and the calls should be fine. Now use http://www.pinvoke.net/default.aspx/kernel32.getversionex and look for the wProductType value. Win8 = VER_NT_WORKSTATION – magicandre1981 Jan 09 '15 at 18:16
