What does WINDOWS NT stand for? 

Windows NT

Windows NT is a family of operating systems produced by Microsoft, the first version of which was released in July 1993. It was a powerful high-level-language-based, processor-independent, multiprocessing, multiuser operating system with features comparable to Unix. "NT" was expanded to "New Technology" for marketing purposes but no longer carries any specific meaning. It was intended to complement consumer versions of Windows that were based on MS-DOS. NT was the first fully 32-bit version of Windows, whereas its consumer-oriented counterparts, Windows 3.1x and Windows 9x, were 16-bit/32-bit hybrids. Windows 2000, Windows XP, Windows Server 2003, Windows Vista, Windows Home Server, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, Windows Phone 8, Windows RT and Windows Server 2012 are members of the Windows NT family, although they are not branded using the name "Windows NT".
