How To Force Windows Applications to Use a Specific CPU
Note: For the most part we do not recommend you changing these settings, and to rather let Windows manage them.
Find your process in the list, right-click on it and choose Set affinity from the context menu.
We’ve previously written about how to create a shortcut that forces an application to use a specific CPU, but this is a way to change it on the fly.
Channing a process affinity means that you limit the application to only run on certain logical processors, which could come in terribly handy if you have an application that is hogging all the CPU. Here’s how to choose the processor for a running application.
Right-click around the Windows taskbar and release Task Manager.
You will see by default almost all apps are allowed to span all the processors in your PC.
That all there is to it.
Just uncheck the ones you don want it to run on and you are good to visit.
Then change over to the details tab.
