WSL was just one exemple. There are literally thousands of other improvements. Not all are revolutionary but at least some matter in a big way to most people. Any gamer would say DirectX 12 is enough to upgrade from Win7 to Win10. Anyone with two screens of different DPI should say the same. Anyone with a Wifi6 router would want to upgrade. The list goes on. I also liked the fast and simple Win2000, or Win7. But I do remember how terrible the screenshot functionality was, how bad the terminal was and how crappy the dpi scaling was. Nostalgic glasses are some times too rosy.

It used to be that the product was office, sql server, exchange and windows was the vehicle to deliver it. It’s really not so different that the products are OneDrive or AppInsights or GitHub.
