Windows NT 4.0 was the last major release to support Alpha, MIPS, or PowerPC, though development of Windows 2000 for Alpha continued until August 1999, when Compaq stopped support for Windows NT on that architecture; and then three days later Microsoft also canceled their AlphaNT program, [60] even though the Alpha NT 5 (Windows 2000) release ...

The Windows NT operating system family's architecture consists of two layers (user mode and kernel mode), with many different modules within both of these layers.. The architecture of Windows NT, a line of operating systems produced and sold by Microsoft, is a layered design that consists of two main components, user mode and kernel mode.
Applications start at a base priority level of eight. The system dynamically adjusts the priority level to give all applications access to the processor. Priority levels 0 - 15 are used by dynamic applications. Priority levels 16- 31 are reserved for real-time applications.
Windows NT uses the two-level system. [20] The real mode programs in 8086 are executed at level 0 (highest privilege level) whereas virtual mode in 8086 executes all programs at level 3. [21] Potential future uses for the multiple privilege levels supported by the x86 ISA family include containerization and virtual machines.
