   Proper way to exit in a batch file
  Recently I decided to try and make a simple batch file so that I could run two programs when I clicked on the batch file and then upon my return exit both of the programs.My startbatch file runs fine, and at first my exit code seems to work, but the next time I run my startbatch file one of the programs gives me a driver error saying it didn't have a chance to unload the driver.Right now my exit patch file uses the tskill pg2.Is this the correct way to exit a program through command?Using windows xp x64
