How can I create "My Computer" toolbar at the top of the Desktop in Windows 7?

In previous versions of Windows, I have been able to "drag and drop" the My Computer icon to the top or sides of the desktop and convert it into a toolbar. The toolbar could be set "always on top" or "autohide". I found this a very convenient way to have instant access to all my drives with NO clicks.
