how do I relate windows system CPU information on model, family, and
step to an actual processor name

Hi,

Thank you for your question.

The short answer is that you don't.

The information given isn't very helpful.

Here is an Intel page explaining such details:

Processors. What is family, model and stepping? 
http://www.intel.com/support/processors/sb/cs-001632-prd24.htm

Here is a page trying to regroup such information:

Identification of x86 CPUs with CPUID support
http://grafi.ii.pw.edu.pl/gbm/x86/cpuid.html

Here is an actual application that should give you everything you want
to know about your CPU:

WCPUID V3

I hope this helps you and answers your question. If you need any more
clarifications please do not hesitate to ask, I will be more than
happy to help.

Thanks.
