Earlier this year, Qualcomm announced that its next-generation chips will be the first to fully support Windows 10, including all the programs built for the x86 architecture. In a recent video, Microsoft demonstrated how both x86 and Universal Windows Platform (UWP) apps would run on ARM chips. It also talked about the underlying technology enabling x86 apps to run on ARM chips with near-native performance.
Windows 10 On ARM Not Like Windows RT - Windows RT launched alongside Windows 8 in 2012. It was basically a version of Windows 8 for ARM chips, and it lacked any support for x86 programs. It primarily targeted tablets, and it was supposed to be the Windows version that would bring Intel some ARM competition in the PC market.
