It's still the foundational underpinning of everything Microsoft does. It's just that the other revenues dwarf it. What still shocks me is that the current developers and management on the Windows teams are so extremely bad at everything they do. It's not like they could not serve ads and shove CoPilot in your face, without making the UI so so sloppy and slow. It's not like they couldn't make Explorer use less memory and start faster, even with preloading, which was introduced in Vista, opening Explorer remains painfully slow.
