How can I use VBScript to determine whether I am running a 32-bit or 64-bit Windows OS?

Question

How do i detect the bitness (32-bit vs. 64-bit) of the Windows OS in VBScript?

I tried this approach but it doesn\'t work; I guess the (x86) is causing some problem

WMIC queries may be slow. Use the environment strings:

Function GetOsBits()
   Set shell = CreateObject("WScript.Shell")
   If shell.ExpandEnvironmentStrings("%PROCESSOR_ARCHITECTURE%") = "AMD64" Then
      GetOsBits = 64
   Else
      GetOsBits = 32
   End If
End Function
