How to control what browser opens when getting an update

Not a big issue, but I would prefer that I.E. did not open when I go to get an update or "help."

It opens whether or not I have any other browsers open.

I could not find any kind of preference in WinSCP to allow one to choose what browser will open. (In Windows, I have Opera chosen in Folder Options, File Types for all web options.)

Thanks.

I'll test it again, but I'm pretty sure the pages open in Firefox on machines, where I have it set as a default web browser.

What happens, if you go to Start > Run and type https://www.google.com/ ?
