write a process-kill script under XP?

Id like info on how to write a script under XP that would automatically end processes forcefully to certain processes that I have running in the task-manager to make it simple to prepare my computer for benchmarking, and maybe even a script to re-activate the programs after im done? Does anyone know how to do this if its possible? thanks

thanks! i forgot to ask what kind of file do save it as once you type it into notepad? .ini? thanks

.bat or .cmd
