Actually, Microsoft designed the new browser that way so that there is more room for browsing. However, if you want the menu bar (the one with File, Edit, View, Favorites, etc) back, follow these steps:
Start Internet Explorer
Press and release the Alt key on your keyboard
The menu bar will be visible, Click the View menu option
Click Toolbars
Click Menu Bar
That will do it. You can't move the menu bar above...
