With the development of 64 bits systems, hardwares, softwares, why the newest windows 8 still have 32 bits option ?? Considering that since 2003, virtually all x86 CPUs already have 64-bit instructions ??

Your question is for Microsoft, not for us. We can't answer it, although the reasons seems to be clear. –  Valentin Apr 5 '12 at 22:33

I suspect the only real argument is their insistence that it'll run on EVERY SINGLE MACHINE that Windows 7 would. –  Shinrai Apr 5 '12 at 23:08

One case would be you only have 32-bit device drivers for some hardware you need. Maybe some telephony boards or industrial data acquisition and control. For the consumer, it's probably not likely you'll need the 32-bit version these days except maybe an old printer.
