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.

"I sure hope they are planning to target only a future 64 bit ARM. It would be annoying if 32 bit addressing gets a new lease on life due to this. Personally, when I write a (linux) program, I generally don't even consider whether it would be portable to a 32 bit machine, just like I don't consider whether it would be portable to a 16 bit machine. I'd like it to stay that way.


The ARM Cortex-A15 MPCore CPU architecture, which is the one aimed at desktops and servers, is a 32-bit architecture. Nevertheless, it does not suffer from a limitation of 4GB of main memory, it can in fact address up to one terabyte (1TB) of main memory.

"

Also important note the 4GB limit on 32 bit OS on a lot of x86 chips is garbage as well. PAE mode. 64gb to 128gb. 32 bit mode.

So 32 bit being limited to 4GB is mostly a market bending nothing more by Microsoft.

So we can expect MS to treat ARM the same as what they do x86. Different versions different limits nothing todo with real hardware limits.
