Idle Process
Despite the name shown, the first process listed in the preceding sample tlist /t output (process ID 0) is actually the System Idle process. processes are identified by their image name. However, this process (as well as process ID 8, named System) isn't running a real user-mode image. Hence, the names shown by the various system display utilities differ from utility to utility. Although most utilities call process ID 8 "System," not all do.
