When you have finished working with a document, you need to save your changes and then close the document. To close a document, select the File menu and then select Close . You can also close a document by clicking the Close ( X ) button on the right side of the document window. If you are working with multiple documents, closing one of the documents does not close the Word application. If you want to completely end your Word session, select the File menu, and then select Exit . Before closing a document, Word checks to see whether it has changed since it was last saved. If it has, Word asks whether you want to save these changes before closing. If you don't want to lose any recent changes, click Yes to save the document.
