title: How to use all the cores in Windows 7?
body: <p>I am not sure if this belongs to Stackoverflow or Superuser but I thought I would ask here.</p>
  
  <p>I have a console based application written in C which currently takes about an hour to terminate in Windows 7 64-bit OS. The task manager reports that the application is using only 25% of the available CPU. I would like to reduce the run time by increasing cpu usage.</p>
  
  <p>Is there any way to let the application use all four cores (the laptop has Core i5) instead of just one? I am assuming that task manager reports 25% because only one core is allocated to the program.</p>
