How to check is the OS is 64 bit or 32 bit?

[Gugle]

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!

I replied in microsoft.public.scripting.vbscript.

The registry setting seems to return info on the OS. I would suggest using
WMI for information on either OS (Win32_OperatingSystem class) or processor
(Win32_Processor class).

Have a look at the answers you received in the VB Scripting newsgroup, then

Hi Pegasus,
Apologies for multi-posting. I was in urgent need of a solution for
this and hence I was trying out different newsgroups.

That's perfectly alright - as long as you cross-post them! Unfortunately you
chose to multi-post them.
