Trayconizer
Trayconizer allows you to minimize virtually any application to the system tray rather than having it take up valuable space in your taskbar. The screen shot to the left shows Trayconizer minimizing Notepad to the system tray. Using Trayconizer is simple. To start Trayconizer on Notepad, you would execute: C:\Path\To\Trayconizer.exe C:\Windows\Notepad.exe. You can create a shortcut in your Startup group to execute Trayconizer on a program that you use frequently but want to keep tucked out of the way in the system tray when you're not using it. There is even an option for starting the application initially in the minimized state. Trayconizer will automatically shut itself down when you close the program you are Trayconizing. Additionally, multiple Trayconized programs are handled by a single instance of Trayconizer to avoid wasting system resources. Trayconizer requires no DLL's beyond the base Win32 API libraries and will not store any entries in your registry.
