Encyclopedic overview

Windows NT 4.0 is a major release of the Windows NT operating system developed by Microsoft, targeting the data server and personal workstation markets. It is the direct successor to Windows NT 3.51, and was released to manufacturing on July 31, 1996, and then to retail in August 24, 1996, with the Server versions released to retail in early September 1996.

Its most prominent user-facing change was the adoption of Windows 95's user interface, introducing features such as the Start menu and taskbar to the Windows NT product line. It also includes various performance and stability improvements to system-level components, as well as new components such as a cryptography API, DCOM, TAPI 2.0, and the Task Manager, and limited support for DirectX. Over its support lifecycle, NT 4.0 received various updates and service packs offering patches, enhancements to its hardware support, and other new components. Two new editions of NT 4.0 were released post-launch, including a modular variant for embedded systems, and the Terminal Server edition. NT 4.0 was the last version of Windows NT to support RISC processors until the addition of ARM support in Windows RT which is based on Windows 8.
