Is there documentation that lists the entries in the class root\CIMV2\Win32_Processor? I am particularly interested in the
values of "Architecture". 

To clarify, I need to differentiate between x86, ia64 and amd64
architectures.

Hi,

Win32_Processor class [WMI]
http://msdn.microsoft.com/library/en-us/wmisdk/wmi/win32_processor.asp

<quote>
Architecture
    Data type: uint16
    Access type: Read-only

    Processor architecture that the platform uses.
    Value 	Meaning
    0 	x86
    1 	MIPS
    2 	Alpha
    3 	PowerPC
    6 	Intel Itanium Processor Family (IPF)

With ia64 I would think you mean IA-32 Intel Architecture processors
with 64-bit extensions, or Intel® Extended Memory 64 Technology
(Intel EM64T), also sometimes referred to as IA-32e.

The Architecture property will return 0 (x86) for an EM64T processor
(and for amd64 as well I think).


To see if an Intel processor supports EM64T, you will need to use
Intel's CPUID instructions to read the extended feature flags in the
EDX CPU register.
