How to determine OS Platform with WMI?

Question

I am trying to figure out if there is a location in WMI that will return the OS Architecture (i.e. 32-bit or 64-bit) that will work across \"all\" versions of Windows. I though

Answer 1

The environment variable 'PROCESSOR_ARCHITECTURE' is all that is needed. Just like the registry call this will return either 'AMD64' or 'x86'.
