Drag the My Computer icon to the Start button, and it will automatically create a cascading shortcut to My Computer that will expand to reveal your drives, folders, and files. This is similar to the Expand Control Panel option new to Windows 2000. With the emphasis on tooltips that Windows 2000 now incorporates, you can also hold your cursor over a partition in the Start Menu for a moment to view its free space and capacity. You can execute a file just by single clicking on it in the Start Menu, and open a folder by double clicking.
This tip works on Windows 2000 Professional and Server.
