How can I perminently run a program with affinity set to one core?

Hi guys,

I want to know how I can perminently run a program with a certain affinity setting that has not been installed, it’s saved in a custom folder. I heard it was possible with a shortcut or batch command made with notepad. I don’t know exactly how to do this with a .exe file that has not been installed.

To make a long story short: I need to perminently run a simple utility on one CPU core. How can I do this?

Thanks in advance.
