<![CDATA[Unable to set as default web browser, Windows 10 x64]]>Hello,
Since few weeks I'm unable to set Opera as my default web browser. It's impossible to run URLs from other apps, like thunderbird and other. I'm on Windows 10 x64 and Opera 51.0.2830.34, Stable x64 (from chocolatey https://chocolatey.org/packages/Opera).

Any ideas?

Such versions do not modify the registry, which makes both tasks you ask about impossible.
