 Processor Affinity - Add Set Affinity to Context Menu
How to Add or Remove "Run with CPU Affinity" to the Context Menu  Information By default, Windows 7 and Vista runs an application on all available cores of the processor. If you have a multi-core processor, then this will show you how to add or remove Run with CPU Affinity from all application files and shortcuts context menu to set processor affinity to an application to control which core(s) of the processor an application will run on.
If the application and CPU supports Symmetric Multiprocessing (SMP) or HyperThreading (HT), then Windows will automatically adjust the application's usage of each processor core for the best performance. You will not gain much, if anything, from manually changing the processor affinity for these type od applications.  Note The affinity changes you make to the current instance of an application or process are only temporary and not set permanently.
Once you close the application or restart your system, Windows forgets your set affinity and automatically sets back the default affinity of the application running on all available cores of the processor.  Warning I have included REG downloads below to add context menu items for up to a 12 core processor. How many cores you actually have will depend on your processor. You can add one or more of any of the following Run with CPU Affinity context menu items below to use as needed. DO NOT ADD A CONTEXT MENU ITEM numbered above how many cores you actually have.
You can quickly see how many processor cores you have by opening Task Manager (CTRL+SHIFT+ESC), clicking on the Performance tab, and counting how many CPU Usage History graphs you have.  EXAMPLE: Run with CPU Affinity Added or Removed from Context Menu
