Microsoft has been trying to make Windows on ARM work for years now. It was a key drive behind "mobile first" efforts back when Microsoft worked hard on Windows Phone. It's been diminished since, but the effort hasn't disappeared. Most recently the Surface Pro X has been a return to Windows on ARM. The Surface Pro X is useful to mention for several reasons including things like Electron on M1 wouldn't have happened so fast if Microsoft hadn't put so much work into Chromium on ARM for Surface Pro X, and also that the Pro X was the first device to ship Microsoft's x86 (32-bit) emulation for traditional Win32 applications. (Microsoft also has in the beta pipeline x64 emulation for Windows on ARM.) Microsoft isn't necessarily in danger of losing their "moat" in any switch/focus to ARM at this point, given the wide variety of applications known to work out of the box on the Surface Pro X today (with more support/compatibility again already in the beta pipeline).
