How To Set Processor Affinity To An Application In Windows 7,Vista,XP

In Windows XP, Windows Vista, and Windows 7 applications by default run on all available cores of the processor. If you have a dual or quad core processor, then you can set affinity to an application to control which core of the processor an application can use, in this way you can assign one application or a program to use only one processor while other application can run on other processor. Although you cannot set priority to system services but you can set affinity to applications like Google Chrome, Firefox or any Anti-Virus, in this way you can achieve a good overall performance.
