For most users, it’d be nearly perfect, hiccup-free compatibility with Windows software and a desktop experience that is identical to that of Windows wherever practical so there is no learning curve. In other words, when users can’t tell they’re not using Windows.

Anything less won’t move the needle, at least in the short term. People don’t like change and they don’t like thinking about their tools. You see this even with macOS, where switchers only put up with learning because there’s immediate tangible benefits like long battery life and reduced heat/fan noise acting as a carrot, and even then sometimes that’s not enough and they end up falling back to Windows.
