Portable code???

Just wondering if Microsoft need to rewrite everything from scratch to get it to work on 64 bit - it's obvious they can't write portable code...

Is that why WinNT ran on MIPS, Alpha, and PowerPC?. Win2K was also ported to Alpha, but was development was cancelled by Compaq.
(quoting the Wikipedia, I know....)

Win2K and up have run on Itanium. Look at the TPC scores for HP SuperDome (highest Superdome score)

XBox 360 runs a custom NT kernel. The developer workstations for XBox 360 are dual Apple G5s running a custom NT kernel.

Windows CE runs on Arm, MIPS, and SH3/4 processors, as well as x86:

By design, anyways, very little of Windows is non-portable. Only the HAL, which deals with interrupts, SMP, etc. is non-portable.
