       Windows Script Host is built into Microsoft Windows 98, 2000, ME and XP. 
       If you are running Windows 95 or NT4, you can download Windows Script 
       Host from the Microsoft Windows Script Technologies Web site at  
       http://msdn.microsoft.com/scripting/. 
       
       Some information is not returned on non-NT-based systems.  A reference set in Projects / References to the Microsoft WMI Scripting Library.  |

        The Win32_Processor WMI class returns processor status and information for both single and multiprocessor machines. This demo and illustration only show some of the available information from the class. For a complete listing see the table in the Comments section below. Note that some systems may not return information in all class properties.  |
