Is there documentation that lists the entries in the class root\CIMV2\Win32_Processor? I am particularly interested in the

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

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.

Thanks for the reply.

From this, can I take that there is no way to differentiate between x86, ia64 and amd64 processors using wmi?
