Windows NT turns 20 today



    Today , system administrators also have something to note: the legendary Windows NT operating system is 20 years old !



    The first release of Windows NT took place on July 27, 1993. It was a fundamentally new system on a new core, which began to be created after the termination of cooperation between Microsoft and IBM over OS / 2 . Redmond’s nosebleed needed to create a new, stable operating system - a platform for decades to come, and they made incredible efforts to do this. The dramatic history of creating the NT kernel by a team led by lead programmer David N. Cutler has been revealed in several books, including “Showstopper! The Breakneck Race to Create Windows NT and the Next Generation at Microsoft ”.

    David Cutler previously led the Digital Research Center with 200 developers, where he created the architecture of the new CPU and the VMS operating system, but Digital closed this project in 1988. Cutler immediately received an offer from Bill Gates, so he moved to Microsoft with a group of 20 Digital employees and embodied many ideas from the VMS and UNIX operating systems in NT. For significant similarities between VMS and NT, see here .

    The NT kernel is still widely used, including in Windows 8, Windows Server 2012, Windows Phone 8, Windows Azure, and even Xbox One, writes Mary-Joe Fowley.

    David Cutler also still works at Microsoft and is one of the main developers of the operating system for the Xbox One, before which he worked on Windows Azure.

    The first version of NT in July 1993 was called Windows NT 3.1. It was followed by NT 3.5, 3.51 and 4.0. Newer versions of Windows continue this numbering .
