How Terminates a Process
Due to issues with security and Windows session isolation, adTempus is generally not able to close a program by sending a "Close" command to its main window and allowing it to close gracefully. Instead, it kills the process, equivalent to using the End Process command in the Processes list in Windows Task Manager.
When a program is terminated in this fashion, it is killed immediately and does not have a chance to do any of the things it would normally do before exiting (things like saving files).
Programs terminated in this manner generally have an exit code of 255.
