Where can I find the Windows version in a CIM instance?-CodePudding

On the Windows Settings > System > About page, the "Windows specifications" section presents the following information.

Edition Windows 10 Enterprise
Version     20H2
OS build    19042.1288

Using the following reports the Version member as 19042.1288.

(Get-CimInstance -ClassName 'Win32_OperatingSystem').Version

Where can 20H2 be found in a CIM instance? I cannot find it in any of the following CIM instances.

CIM_OperatingSystem
Win32_OperatingSystem
Win32_SystemOperatingSystem

CodePudding user response：

Indeed, the so-called display version - such as "20H2" - doesn't seem to be a part of the Win32_OperatingSystem (CIM_OperatingSystem appears to be just an alias) and Win32_SystemOperatingSystem CIM (WMI) classes (as of Windows 10 20H2), but you can obtain it from the registry:

Get-ItemPropertyValue 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion' DisplayVersion

Similarly, the release ID - such as "2009" - is seemingly also only found in the registry:

Get-ItemPropertyValue 'HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion' ReleaseId
