Windows branding is now forever tied with x86/x64 Win32 legacy compatibility, meanwhile WSL had captured back a lot of webdevs from Mac. Google continues to push Chrome, but Electron continues to grow side by side. Lots of stuff happening with AI on Linux too, with both Windows and Mac remaining to be consumer deployment targets. Phone CPUs are fast enough to run some games on WINE+Bochs.
At this point, would it not make sense for MS to make its own ChromeOS and bolt-on an "LSW"?
