'''Xenix''' is a discontinued [[Unix]] [[operating system]] for various [[microcomputer]] platforms, licensed by [[Microsoft]] from [[AT&T Corporation]]. The first version was released in 1980, and Xenix was the most common Unix variant during the mid- to late-1980s. The [[Santa Cruz Operation]] (SCO) acquired exclusive rights to the software, and eventually replaced it with SCO UNIX, later known as [[OpenServer]], with the final Xenix version released in 1991.
