Between Apple Silicon and Chromebooks, it's looking like ARM-based computing is becoming a thing, or at least enough of a thing that if I was Microsoft, I'd worry about how much Windows is tied to x86.

And while Windows does have an ARM port, all the drivers and board support packages seem to be tied to Linux, and Linux based operating systems like ChromeOS and Android.

What I suspect to see is a product that combines the Linux kernel, ELF versions of Edgium and Office, a port of the Windows shell that runs on top of this, and maybe support for running Win32 binaries in emulation, with as-it-is backwards compatibility guarantees.

If something like this comes to exist, I'm guessing it will be sold as Windows A, or something other name like that. Will it be Windows? That's probably a philosophical question, more than anyththing.
