I recently had to use Windows 10 for some .NET work and found it really surprising that it nags so much when changing the default browser. Not just in the control panel prompt, but repeatedly afterwards via notifications and even on the login screen.

Hint: Your OS shouldn't do this. It should stay out of your way and honour your choices.

The Windows login screen does other startling things, too. I have also seen it display sneaky advertising for Netflix.
