WinOS

WinOS is an operating system initially created by Microsoft during the time Windows 3.1 was being developed. The OS was announced on November 17, 1991. Each version was released roughly on a yearly basis. In 1996, Apple Inc. became inspired by the heyday of WinOS. They later developed AppOS, which are Apple’s counterpart of WinOS. The combination of WinOS 6.5 onwards being notoriously unstable and sold poorly along with the success and progress of AppOS versions, led to it being discontinued in early 2002.
