Vista - How to check if the OS is 64 bit or 32 bit?

Hi all,
I want to check if the OS is 64 bit or 32 bit using vbscript. I'm
currently reading the registry key - HKEY_LOCAL_MACHINE\SYSTEM
\CurrentControlSet\Control\Session Manager\Environment
\PROCESSOR_ARCHITECTURE and checking the architecture. My question is
- Will this return the architecture of the OS or the architecture of
the processor? i.e., if a 32-bit Windows OS is installed on 64 bit
Processor, what will this return?

Thanks in advance for your help!

with 32-bit Vista.

===========
Option Explicit

Dim strComputer, objWMIService, colSettings, objProcessor

strComputer = "."

Set objWMIService = GetObject("winmgmts:" _
& "{impersonationLevel=impersonate,authenticationLevel=Pkt}!\\" _
& strComputer & "\root\cimv2")

Set colSettings = objWMIService.ExecQuery _
("SELECT * FROM Win32_Processor")

For Each objProcessor In colSettings
Wscript.Echo "System Type: " & objProcessor.Architecture
Wscript.Echo "Processor: " & objProcessor.Description
Next
======
You can parse objProcessor.Description for "x64" to check for 64-bit (or
"x86" for 32-bit). The system type (objProcessor.Architure) returns 9 on my
machine, but I need to research what the number means.
