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.

"So 32 bit being limited to 4GB is mostly a market bending nothing more by Microsoft.
Lolwut? Windows' 32bit client versions do PAE but limits the *operating system* to 4GB anyway due to problems it caused with instability with some drivers (Windows Server 32bit do support more than 4GB).
...
However, *applications* in 32bit Windows can access more than 4GB if they want to using AWE (Address Windowing Extensions).
"

A Windows client SKU won't address more than 4Gb of physical memory. This means that applications can't use those physical pages either. If an app can use those physical pages, you'll have those pages going through device drivers, which is what the article claims is not supported. If an application attempts to address more than 4Gb of memory, this can only be achieved by paging (ie., giving more than 4Gb of virtual address space but without more than 4Gb of physical pages.) So if you want to put 8Gb of RAM in a machine and actually use it, you have to choose between a 64-bit client SKU or a 32-bit server SKU; a 32-bit client SKU will not use half of that memory.

In other words, you're talking out of your ass.
