`Microsoft Releases Windows 3.1
`
`Microsoft Corporation releases Windows 3.1, an operating system that
`provided IBM and IBM-compatible PCs with a graphical user interface
`(though Windows was not the first such interface for PCs). Retail price was
`$149.00. In replacing the previous DOS command line interface with its
`Windows system, however, Microsoft created a program similar to the
`Macintosh operating system, and was sued by Apple for copyright
`infringement. (Microsoft later prevailed in this suit).
`Windows 3.1 added multimedia extensions allowing support for sound cards,
`MIDI, and CD Audio, Super VGA (800 x 600) monitors, and increased the
`speed of modem it would support to 9600 bps. It also finally abandoned
`"Real Mode," a vestigial environment dating back to the 8086 CPU. It
`provided scalable fonts and trapped the "three finger salute" (CTRL-ALT-
`DEL), prompting the user to avoid inadvertent re-boots. It also refined its
`OLE (Object Linking and embedding) concept, allowing users to cut and
`paste between applications.
