How do I Find the Number of Core Processors in Windows?

A computer processor, or CPU, is the device in a computer that runs programs and performs calculations. Processors only run programs one at a time; processors switch between programs to provide multitasking. However, this decreases performance when running multiple CPU-intensive tasks at once, such as encoding a video while running a computer game. Processor manufacturers increase a processor's multitasking performance by designing newer CPUs with multiple cores; each core functions and appears as a separate CPU in Windows. Find the number of processor cores on your computer using the Windows Device Manager.

Skill level:


  1. 1

    Open the System control panel by clicking "Start," right-clicking "Computer" and clicking "Properties."

  2. 2

    Open the Device Manager by clicking "Device Manager" in the left sidebar of the System control panel window.

  3. 3

    Expand the list of processors by clicking the arrow to the left of "Processors" in the Device Manager Window.

  4. 4

    Count the number of processor entries under "Processors." Each core appears as a separate processor on a separate line, although they all have the same name. For example, the same processor name listed four times indicates the processor has four cores.
