Here's one for Vista users.......'cos they broke it
In XP I always have a 'my computer' toolbar, set to on top and autohide etc but running up the left side of the screen...it's useful to just mouse over to the left and select a drive (I've got 8

) or a dvd device etc......
In Vista you cannot move the quick launch toolbar to the left, or create toolbars there, so there's a workaround;
1. Right-click on a blank area of the desktop
2. Select New Folder from the context menu
3. Drag this New Folder to the very side of the screen and let go. The toolbar should run vertically down the side of your desktop.
4. Right-click this new toolbar and select Toolbar and then Quick Launch, My Computer etc
5. Right-click this new toolbar again and unselect New Folder
6. If you're intending to move the quick launch to the side rather than create a new toolbar there, right-click taskbar at the bottom of the screen, select Toolbars, and unselect Quick Launch.
