Microsoft Works Suite 2001 provides much of the functionality of the more full-featured Microsoft Office business software suite at a price, size, and design more appropriate for home users. Included in the package are the Microsoft Works spreadsheet program, the 2000 edition of Microsoft Word, the standard 2001 edition of the Microsoft Encarta encyclopedia, and the Microsoft Picture It! digital image software, as well as Microsoft Streets and Trips 2001 and Microsoft Money 2001. This full version of the program ships on one DVD disc and installation requires a DVD-ROM drive. Users that have installed a full version of Microsoft Works can often later purchase upgrades to subsequent versions at a significantly lower cost.
