A. In Windows XP, the new version of shutdown.exe (the tool used to shutdown/reboot from the command line) contains support for tracker descriptions via the -d (description/reason code) and-c (comment) attributes. For example,

                              shutdown -t 10 -d up:125:1 -c "Testing"                              
shuts down the system in 10 seconds, with a description of user-defined, planned, major reason 125, minor reason 1, and a comment of "Testing."
