> So while a regular PC will boot up and immediately run all of the services necessary to run a Win32 application, for example, Windows 10X won’t load this subsystem until it’s needed. This, the company argues, allows it to be very efficient with the resources available on the machine and extend its battery life significantly.
Exactly; they got that out of their system with Windows RT. (And apparently the upcoming Windows 10 for ARM will ship with Win32 support via emulation.)
Win32 is an OS API, which doesn't necessarily relate to the CPU or other chipset members. Do you mean it will Win10 for ARM will support code targetted at ia32/amd64 CPUs via emulation?
In the event you are not joking, there are entire industries running on Win32. My industry alone (EDA) is a 100B dollar industry. I'm aware of many others.
Hopefully they won't decide it is never needed.
