When you book a vacation and the hotel comes with a buffet, you know you're not getting the best restaurant in town, but you might opt for it because it's easier: You don't have to make a bunch of conscious choices and incur risk, you let someone else make that choice for you. When the sausage tray is always empty, you blame yourself for being cheap.

Windows is the buffet that comes with your new PC.

You didn't order ads, telemetry and questionable UX?

Don't worry, it's included in the price.
