@mischievoustomato >if riscv replaced x86 then MS would definitely port Windows to it
AMD64 has already replaced x86, but m$'s code is so good that a bunch of stuff is still 32 bit.

I doubt RISC-V's going to replace AMD64 for proprietary things, but if that somehow happens, yes, m$ would be forced to port windows to it no matter how hard the codemonkeys need to suffer.
