As you work in Microsoft Excel 2010, remember to save your work often or you risk losing your data if the computer crashes or the power goes out. When you save an Excel workbook for the first time, you see the Save As dialog box. The appearance and functionality of the Save As dialog box varies depending on whether you're running Excel 2010 on Windows 7 or Vista or on Windows XP.
