The orriginal target processor—the Intel i860, code-named N10 ("N-Ten") and that was what NT was called inisde Microsoft. i860 was a lousy for hosting OS but awesome for graphics. Soon that was abandoned and NT tageted x86, MIPS, Alpha, PowerPC, Itanium, x86-64 and ARM coming in later releases.

Sadly that means over a quarter century of windows on ARM and it's still not right. Sigh.
