To save your current working document, select/click the Microsoft Office Button located in the upper left hand corner (Figure 1).

A dropdown menu will then be displayed. From the menu, select the Save As button. You can then choose from the options given but I highly suggest saving the Word document as a Word 97-2003 document. By saving your current working document as a Word 97-2003 document will enable you to open the document up using Word 97-2003. If you save the document at a 2007 Word document you will not be able to open it using any previous Microsoft Office Word applications.
