I can't change the default apps in Windows 10

Since a few days ago I can't change the default applications on Windows 10, and that applies to file extensions as well.

This is a gif showing what happens when I try to change the default internet browser

I have Windows 10 Home Edition, Version 1511 (OS Build 10586.164).

I've looked around and I haven't found anyone with this problem, I don't know what to do and It's really annoying.

If someone could help me with this I would really appreciate it.

Solution 1:

I struggled with this too, because using Settings > System > Default apps has no effect for me, and using Explorer > Right Click > Open With > Choose Default Program also has no effect. For me, the venerable Control Panel did the job.

Control Panel > Default Programs > Set Your Default Programs

Not only is the Control Panel interface more powerful, but its settings actually have an effect.
