Windows And this is part two of the story: Microsoft has just confirmed the next version of Windows NT (referring to it as NT for clarity's sake) will be available for ARM - or more specifically, SoCs from NVIDIA, Qualcomm, and Texas Instruments. Also announced today at CES is Microsoft Office for ARM. Both Windows NT and Microsoft Office were shown running on ARM during a press conference for the fact at CES in Las Vegas.

RE[4]: enough bits?

64 bit kernel is not necessary, see OS X. X86-64 CPU's can switch between two modes of operations at run-time allowing 64 bits processes as well as a 32 bit kernel and drivers.

Maybe you could, but once you get enough 64-bit support in the kernel to be able to run 64-bit processes, it's just weird to keep the rest of the kernel 32-bit.

Moreover, drivers and kernel could only write in the first 4GB of RAM without being PAE-aware, which could be problematic for things like DMA.

Yeah, I know about the hybrid mode that AMD CPUs can work in.

But, I thought it was only the other way around. You could run 32-bit userland on a 64-bit kernel. Not that you could run a 64-bit userland on a 32-bit kernel.
