How do I find out how many processors are recognized on my Windows XP machine?

I would like to get more detailed information about my processor(s) in Windows for debugging, along with information about the processor family, make, and stepping version.

One way to obtain this information is to run the Microsoft "System Information" application. Go to the Start Menu => Run and execute 'msinfo32'. The application will display a summary of information about the machine. Look to see how many "Processor" lines appear in that summary under the "System Summary" option.

As an example, following these steps on an Intel Quad Core machine shows the following:

 OS Name   Microsoft Windows XP Professional

 Version   5.1.2600 Service Pack 2 Build 2600

 OS Manufacturer   Microsoft Corporation

 System Manufacturer   Hewlett-Packard

 System Model   HP xw4600 Workstation

 System Type   X86-based PC

 Processor   x86 Family 6 Model 15 Stepping 11 GenuineIntel ~2400 Mhz

 Processor   x86 Family 6 Model 15 Stepping 11 GenuineIntel ~2400 Mhz

 Processor   x86 Family 6 Model 15 Stepping 11 GenuineIntel ~2400 Mhz

 Processor   x86 Family 6 Model 15 Stepping 11 GenuineIntel ~2400 Mhz

 BIOS Version/Date   Hewlett-Packard 786F3 v01.03, 9/28/2007
