The native API is largely undocumented, and noted by the prefixes Rtl, Zw, and Nt. Windows NT is a micro kernel design that supported the following subsystems: Betas were then released in July of 1992, at the Professional Developers Conference in San Francisco, followed up with another beta in October 11th, of 1992. With NT OS/2 renamed to Windows NT, the first public demonstration was the October 1991 Comdex developers pre-release, followed up by the December 1991 pre-release. This started the rift that would end the Microsoft IBM collaboration. The 16 bit emulation for OS/2 applications remained, however the Graphical Interface for OS/2 programs became a separate product. However after the 1990 release of Windows 3.0, Microsoft started to shift the primary API of NT OS/2 to the Windows API.

It was quickly apparent though that the i860 was NOT going to be a good workstation CPU, and the effort was quickly moved to the MIPS CPU, and Microsoft built their own motherboard design the JAZZ. This is where the NT in NT comes from, processor they used was called the 'N-Ten' from the i860 XR processor. This was done to keep Windows NT portable, and not fall into i386'isims into the original base source. NT OS/2 was originally targeted to the Intel i860 CPU.

It is important to remember that the NT project started in 1988, and where Microsoft was product wise. Microsoft hired Dave Cutler away from Digital to help with the implementation of the OS, back in 1988. The goal was to design a micro kernel OS that could run 32 bit POSIX binaries, 16 bit OS/2 1.x binaries, 16 bit MS-DOS & Windows binaries with an improved 32bit OS/2 API & Windowing system. Originally it was a future thinking version of OS/2 that would be portable, and was targeted for the coming RISC CPUs.
