It's quite simple to find the name of the operating system with PowerShell.  The WMI cmdlet GetWmiObject contains a lot of useful information about the environment, there's numerous ways to use the object but here's one method:

 (Get-WmiObject Win32_OperatingSystem).name

This should work straight away but for me I encounted some "weird" issues which suggested there were some problems with my Windows installation and specifically the WMI repository.  Intially I received the following error: running the above command:

 InvalidOperation: (:) [Get-WmiObject], COMException

Here's what I did to fix the problem:

 

  • Acertain if there is a problem with WMI (C:\Windows\System32\wbem)
    winmgmt /verifyrepository
  • This this should show you if there are any issues with WMI, this came back and said everything was ok when clearly it wasn't!...
  • I rebuilt the repository in PowerShell
     winmgmt /resetrepository  
 Restart-Service winmgmt -Force
