Are there any articles from Microsoft folks on why they made the 32/64 compatibility choices they did? I'm not going to say they're the worst, and they certainly work, but they're also pretty obtuse and "Why would you design a thing like that?" From memory of the era, the 32/64 bit client transition seemed a bit rushed when Intel had long decreed no home users would need 64-bit, and then AMD promptly started selling the Athlon 64 to anyone who would buy one. So maybe just time pressure?
