When I upgraded my default changed from Chrome to Edge. When I clicked on my first URL, also in an email, it did not give me any choices which was kinda frustrating. Opening Chrome also didn't give me the whole "Chrome is not your default; do you want it to be?" dialog.

When I upgraded it gave me a page showing me the new defaults it was about to apply, and gave me the option to skip it and keep what I was using before.

Went with the latter option and indeed, it's still all MPC-HC, foobar2000 and Opera.

Maybe it's because I was upgrading from 8 you were upgrading from 7? I recall some changes to how defaults were handled between them.

Nope, upgraded from Windows 8.1. Not sure why I had a difference experience than you. I even went through the customize screens.

Which edition do you have? Windows 8, Pro, Enterprise, or RT?

I did the upgrade with Win 8.1 Pro and the choice to reset default program options was pretty clear.

Windows 8.1...home? I forget what they called non-pro.

Hmm, interesting, I was doing an upgrade from 8.

I wonder if Windows 10 doesn't support reading off whatever structure is used for defaults in Win7.

Oh I'm aware as that's where I had to change it (chrome didn't give me a "make default" button which makes me wonder if that's not possible in Windows 10).

It's not possible. Microsoft intentionally removed the API that allowed web browsers to offer that option in Windows 10.
