title: get-CimInstance for powershell 2.0
body: <p>What is the equivalent of Get-CimInstance Win32_OperatingSystem for powershell 2.0? Or maybe the equivalence to get relent data to know if a computer is running Windows 7 or 8. Right now I use get-ciminstance to the version. 6.2 is windows 8 and 6.1 is windows 7.</p>
