Taskbar Hide, hide program windows completely with a hot key, or minimize programs to the system tray instead of keeping icons in your taskbar. Hide some less used icons from the system tray. Change the icon and title of any window. Set any application to always be on top, and show the properties of an application, such as Windows handle, class name, or process ID. Hide the taskbar, the Start button, a task window, the system tray, or the clock. This program also can maximize or minimize all windows or only IE windows.
