Windows NT 4.0 is a preemptively multitasked,graphical operating system, designed to work with either uniprocessor or symmetric multi-processor computers. It was part of Microsoft's Windows NT line of operating systems and was released to manufacturing on 31 July 1996. It is a 32-bit Windows system available in both workstation and server editions with a graphical environment similar to that of Windows 95.

The successor to Windows NT 3.51, Windows NT 4.0 introduced the user interface of Windows 95 to the Windows NT product line, including the Windows Shell, Windows Explorer (known as Windows NT Explorer), and the use of "My" nomenclature (e.g. My Computer). It also includes most applications introduced with Windows 95. Internally, Windows NT 4.0 was known as the Shell Update Release (SUR). While many administrative tools, notably User Manager for Domains, Server Manager and Domain Name Service Manager still used the old graphical user interfaces, The Start Menu in Windows NT 4.0 separated the per-user shortcuts and folders from the All users shortcuts and folders by a separator line. Windows NT 4.0 includes some enhancements from Microsoft Plus! for Windows 95 such as the Space Cadet pinball table, font smoothing, full window drag, high color icons and stretching the wallpaper to fit the screen. Windows Desktop Update could also be installed on Windows NT 4.0 to update the shell version and install Task Scheduler. The Windows NT 4.0 Resource Kit included the Desktop Themes utility.
