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[6]: enough bits?

It's not this simple.

I don't know how Microsoft implemented this in practice, but the way I see it they only have a few choices :
-Having application developers swap data in and out of their application's address space all by themselves (cumbersome)
-Having applications not directly access their data, but only manipulate it through 64-bit pointers which are sent to the operating system for every single operation. They can do that e.g. by having the extra RAM being manipulated as a file (slow because of the kernel call overhead)

Really, PAE is only good for multiple large processes which each use less than 4GB. Having an individual process manipulate more than 4GB on a 32-bit system remains a highly cumbersome operation.
