Answer 1

On Windows this kind of stuff can be recovered directly from the registry (regedit).

Search the web to find out the specific registry paths, like this.

Answer 2

If you look at the documentation for QDesktopServices::openUrl() you will see that:

If a mailto URL is specified, the user's e-mail client will be used to open a composer window containing the options specified in the URL, similar to the way mailto links are handled by a Web browser.

So using QDesktopServices::openUrl() you should be able to open both the default navigator and default mail client.

I assume you want to open these applications and not just find out what they are.
