HOW-TO: Open Microsoft Office 2007 documents using older version of Microsoft Office

You may soon encounter documents saved by Microsoft Office 2007. The newly released productivity suite saves its documents in new formats by default for added functionality which you may or may not care. To open these documents using an older version of Microsoft Office (i.e. Office 2000, Office XP and Office 2003), install the free Microsoft Office Compatibility Pack for Word, Excel, and PowerPoint 2007 File Formats.
