Microsoft Office Word
Microsoft Word is a word processor developed by Microsoft. It was first released in 1983 under the name Multi-Tool Word for Xenix systems. Subsequent versions were later written for several other platforms including IBM PCs running DOS (1983), Apple Macintosh running Mac OS (1985), AT&T Unix PC (1985), Atari ST (1988), SCO Unix (1994), OS/2 (1989), and Microsoft Windows (1989). Commercial versions of Word are licensed as a standalone product or as a component of Microsoft Office, Windows RT or the discontinued Microsoft Works suite. Freeware editions of Word are Microsoft Word Viewer and Office Online, both of which have limited features.
