Some of the early RISC designs included more instructions in their ISA than their CISC counterparts.
This has nothing to do with the point made in the post to which you responded.
The Loongson CPU includes a lot of support in terms of extra macro-instructions in order to assist with x86 emulation, and still it achieves only 70% of native performance.
ARM does not include any such support at all, so x86 must be entirely emulated in software.
Hence, the performance of a low-power ARM chip running x86 binaries under emulation will be dismal. Hence, copies of x86 binary executable applications will be utterly useless the Windows on ARM.
Hence, Windows on ARM will not have the benefit of the existing corpus of x86 Windows applications.
That was the point.
