What happens when you're sharing work with people who use an older version of Word? Word 2003 and 2000 are supposed to detect when you first try to open a DOCX file, then prompt you to download and install an Office 2007 Compatibility Pack. After you've done this, the older Word should convert your Word 2007 files and remove incompatible features. When you reopen that same DOCX file again in Word 2007, the file's original elements are supposed to stay intact. On the other hand, if you open an older DOC file within Word 2007, it will also run in Compatibility Mode, shutting off access to some of the newer program features, which explains why two documents within Word 2007 may display different formatting options.

Boxed editions of Microsoft Office 2007 include a decent, 174-page Getting Started guide. During the first 90 days, you can contact tech support for free, and help at any time with any security-related or virus problems also costs nothing. Beyond that, paid support costs a painfully high $49 per telephone or e-mail incident. Luckily, Microsoft's online help is excellent, although we're displeased that Microsoft and other software makers are increasingly promoting do-it-yourself assistance. We especially like the Command Reference Guide for Word, which walks you through where commands have moved since Office 2003. You can also pose questions to the large community of Microsoft Office users via free support forums and chats. Microsoft Office Diagnostics tool, included with the Office 2007 suites, is also designed to detect and repair problems if something goes haywire. sequential numbering using word
