TrayDevil is a Window to Tray Minimizer with a set of powerful extra tools: It can Hide the TrayClock, disable a window’s Min, Max and Close button, set windows On Top, Shutdown, Restart, Stand By, Hibernate, LogOff, Lock your system and Turn Off your Monitor.
TrayDevil can also automatically run a program (e.g. backup) before it shuts down your system, triggered by a CPU-usage threshold.
TrayDevil is Freeware and was tested on Windows 95/98/NT4/2000/XP/2003
