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.
