Lol, Open Task manager, and go to view--> set columns, Click pid. Its diff, IM stands for Image name. basically the name for the .exe file. You can rename this and the bat file not work (if you're using it to get rid of annoying malware or something..., the image name could change.( It could rename the exe or make another copy)) With PID, the number is given to the individual file. So yea. its better :]
