32-bit platforms

In adjustment to anticipate Intel x86-specific cipher from bottomward into the operating arrangement by developers acclimated to developing on x86 chips, Windows NT 3.1 was initially developed application non-x86 development systems and again ported to the x86 architecture. This assignment was initially based on the Intel i860-based Dazzle arrangement and, later, the MIPS R4000-based Jazz platform. Both systems were advised internally at Microsoft.27

Windows NT 3.1 was appear for Intel x86 PC compatible, DEC Alpha, and ARC-compliant MIPS platforms. Windows NT 3.51 added abutment for the PowerPC processor in 1995, accurately PReP-compliant systems such as the IBM Power Series desktops/laptops and Motorola PowerStack series; but admitting affairs amid Michael Spindler and Bill Gates, not on the Power Macintosh as the PReP adjustable Power Macintosh activity bootless to ship.

Intergraph Corporation ported Windows NT to its Clipper architectonics and after appear ambition to anchorage Windows NT 3.51 to Sun Microsystems' SPARC architecture,28 but neither adaptation was awash to the accessible as a retail product.

Only two of the Windows NT 4.0 variants (IA-32 and Alpha) accept a abounding set of account packs available. All of the added ports done by third parties (Motorola, Intergraph, etc.) accept few, if any, about accessible updates.

Windows NT 4.0 was the aftermost above absolution to abutment Alpha, MIPS, or PowerPC, admitting development of Windows 2000 for Alpha connected until August 1999, back Compaq chock-full abutment for Windows NT on that architecture; and again three canicule after Microsoft additionally canceled their AlphaNT program, alike admitting the Alpha NT 5 (Windows 2000) absolution had accomplished RC2 (build 2128).

Microsoft appear on 5 January 2011 that the abutting above adaptation of the Windows NT ancestors will accommodate abutment for the ARM architecture. Microsoft approved a basic adaptation of Windows (version 6.2.7867) active on an ARM-based computer at the 2011 Consumer Electronics Show.29

According to Microsoft, it is a accepted delusion that the Xbox and Xbox 360 use a adapted Windows 2000 kernel.30 They affirmation that the Xbox operating arrangement was congenital from blemish but accouterments a subset of Windows APIs. The abstraction that it does, indeed, run a adapted archetype of the Windows atom still persists in the community.
