Some people may miss the MENUBAR from the “classic” setup. In the MENUBAR, there are many goodies that will save you time from searching all over the ribbon.
To turn on the menubar:
In the command line;
MENUBAR <enter> 1 <enter>

TASKBAR
At the bottom of the screen when AutoCAD is open, there is an Icon that shows that AutoCAD is currently running. If you have multiple drawings open at the same time, it is easy to navigate from one drawing to another by turning on the TASKBAR in AutoCAD.
Windows 7, however, compared to Windows XP doesn’t show each drawing in their own icon with the drawing name. It just shows that their are multiple drawings open.
To turn on the taskbar:
In the command line;
TASKBAR <enter> 1 <enter>
