Backstage View

Office 2007 introduced the Microsoft Office Button office button which replaced the file menu in earlier versions of Microsoft Office. Howerever, there were some that found this confusing and counterintuitive. Therefore, Microsoft decided to replace the Microsoft office Button with the File tab.

Now when you click on the File tab you are sent to the Microsoft Office Backstage view. The Backstage view is where you manage your documents and related data about those documents - create, save, and send documents, inspect documents for hidden metadata or personal information, set options such as turning on or off AutoComplete suggestions, and more.

As you can see, the options are very similar to those found while clicking on the Microsoft Office Button office button in Office 2007.
