It’s not easy to confirm that your PC has the microprocessor you bought. Even if you crack open the case, the microprocessor hides behind the little fan hat that it wears — and the microprocessor chip under that hat has a lot of numbers and names printed on it that may not be of any use to you.

One way to discover which type of microprocessor dwells in your PC’s bosom is to use Windows. The System window shows a brief microprocessor and RAM summary, similar to the one shown in this figure. You can access the System window in a couple of ways:

  • Press Win+Break on your keyboard (that’s the Windows key plus the key labeled Break or Pause Break).

  • Right-click the Computer icon on the desktop and then select Properties from the pop-up menu.

Not every System window displays very complete information. When Windows doesn’t really know, it may say something vague, such as x86 Family.
