What do you mean by classic mode? Not for Start button, or desktop. If you mean have a computer,networks shortcut on the desktop, you can do that. Just drag the icon to the desktop, and it will ask if you want to create a shortcut. If you mean classic view for control panel, yes again, just choose the view by: twistie, and instead of categories, choose either large or small icons. You can turn off Aero, also and choose in personalize to turn off the widgets dock. If you are talking the search bar it is actually a search bar and a run bar.
