Aviassin Taskbar Eliminator is a great utility which will simply and efficiently remove the taskbar from Windows XP, Windows Vista, or Windows 7.
With just the click of a button or a hotkey, the taskbar is disabled from any side of the screen, providing the freedom to use any dock application, increase computer security, or allow all sorts of Windows customizations. The taskbar can be toggled on and off in real-time, providing the flexibility to quickly view the taskbar to perform an action.
The application interface is simple and easy to understand, allowing it to be used by even the most novice of users. Simply press and hold Control+Alt+T to bring up the Preferences window, from which all options can be adjusted. Press and hold Alt + T to immediately show or hide the taskbar directly.
Taskbar Eliminator can easily be set to start with Windows, so your taskbar is automatically hidden before your computer is even started up.
