Windows NT 3.1 (codenamed Razzle) is the first version of Windows NT. It had a very similar interface to Windows 3.1 but unlike Windows 3.1, Windows NT 3.1 was a complete 32-bit operating system while Windows 3.1 was mostly a constrictive 16-bit environment, although it also included 32-bit components to take advantage of the 386 processor. The name NT officially stands for "New Technology", although it has also been explained to stand for N-Ten, the codename for the Intel i860 processor that NT was originally designed for. It was succeeded by Windows NT 3.5 in 1994. Several update packages were released for NT 3.1 during its lifetime.
Microsoft initially developed NT with the intention to use it as the base for OS/2 3.0, with the project being also known as NT OS/2 or Portable OS/2. However, with the high sales success of Windows 3.0, Microsoft changed the NT OS/2 plans to turn it into a 32-bit version of Windows with a subsystem to run existing OS/2 apps, which has contributed to the end of the IBM-Microsoft partnership. Afterwards, the project was commonly referred to as Advanced Windows in the press before the final name of Windows NT was revealed. The operating system was publicly demonstrated for the first time at COMDEX in October 1991. At the Win32 PDC conference in June 1992, Windows NT was demonstrated for the x86 and MIPS processors. On 27 July 1993, Windows NT 3.1 was released for x86 and MIPS, followed by the DEC Alpha version in September. The Workstation version was sold at $495 while the server version was $1495.
The boot screen only shows the processor count if a multiprocessor kernel and HAL is being used, which would be the case on systems like the Compaq SystemPro/XL and its clones.[2]
