You cannot alter the appearance of the Ribbon in Microsoft Office applications, but you can make some customization changes. For example, you can work with the Quick Access Toolbar, which is customizable; you can add/remove all the commands you like. To do this, you simply need to select the down-arrow next to the toolbar that allows you to choose from the following options:
Minimize the Ribbon - This allows you keep your Ribbon tabs visible, while allowing you a little more room at the top of your screen. The Ribbons will reappear if you select the ribbon tab.
Show below the ribbon - The Quick Access toolbar will grow as you add buttons to it, but you may not want it all the way at the top of your document. You can give it a bit more space to expand if you put it below the Ribbon.
More Commands - This takes you directly to the Customize settings that will allow you to add more commands to your toolbar
If you want to do more with the Ribbon, you can customize it without being a programmer. You just need the Ribbon Customizer™ and ToolbarToggle™ add-ins for Office. Both add-ins let you customize the Office interface, and both can display a version of the menus and toolbars found in Office 2003 and earlier.
