Microsoft is losing Builders fast. They’re switching to MacOS and Linux. The biggest pull keeping people on Windows, outside of shear inertia, is content creation and gaming. However, even these are falling to Linux.
Without Builders, you don’t have software, and without software, you don’t have users. This is why Microsoft needs Windows Lite.
Unfortunately, a fair chunk of my convenience comes from the .NET runtime, but sure, removing the rest would be welcome. I highly doubt they’d bother to do this, though, because so many businesses with higher-tolerance older CEOs are fine with remaining on Windows…
