Just right click anywhere in a folder select New->Shortcut.
As the path to the shortcut, write this:
%windir%\system32\RunDll32.exe shell32.dll,Control_RunDLL hotplug.dll
Now, whenever you double-click that shortcut, it will open up the “Safely Remove Hardware” dialog.
You can actually do better by selecting “Properties” from the context menu of the shortcut, and assigning a hotkey for it. Now, you don’t need to search for the icon in the system tray. You just have to press a hotkey. Hope it increases your productivity a little bit. 
By the way, you can also execute the path above programmatically to get the “Safely Remove Hardware” dialog.
