Info About Microsoft Works

Microsoft Works is a home productivity suite that includes word processing, spreadsheet, and database functionality. It also includes a calendar, dictionary, and other features. Works is often viewed as a trimmed-down version of MS Office. While Works uses its own file formats, newer versions of the program can open and save files in standard Office formats as well.
