Windows NT 4.0
Windows NT 4.0, a successor to Windows NT 3.51,
is preemptive, graphical and business-oriented
operating system designed to work with either
uniprocessor or symmetric multi-processor
computers. It was released to manufacturing on
31 July 1996 (public release on 24 August 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
"NT" designation in the product's title
initially stood for "New Technology" according
to Microsoft's then-CEO Bill Gates, but now no
longer has any specific meaning.
