History
In late 1993/early 1994 Microsoft was working on the next versions of Windows NT after Windows NT 3.1. They had 2 projects, one, codenamed Windows Daytona, which was planned to be released in mid-late 1994, and another, codenamed "NT Ninety-Five", scheduled for release sometime in early 1995. As development progressed, and Daytona, which became NT 3.5, got closer to release, development teams could focus more on NT Ninety-Five, which would have a lot of improvements, taken from the NT 3.5 codebase, being developed at the same time. After NT 3.5 released in September 1994, development focus shifted to NT Ninety-Five, which was eventually rebranded to Windows NT 1995 in September/October of 1994. Around the same time, some code from the then in development Windows Chicago was added to the NT 1995 project, and a prototype start menu shell was added. When Windows NT 1995 released on March 29, 1995, it came with an revamped version of the prototype start menu, which was closer to the final one used when Windows 95 released later in the same year. From 1996-1998, 3 service packs were released, and extended support ended on April 15, 2005, just over 10 years after the operating system had originally released.
