Default text editor

[Frankie]

I want to change the default Stunnel editor from Notepad to Vim.

In Windows (Win+I) I have the default text app set to Vim.
That way, doubleclicking on *.conf or *.txt opens up in Vim.

But Stunnel opens up stunnel.conf in Notepad, not Vim.
Stunnel: Configuration --> Edit Configuration
How can I change that?

I googled first, and can't find any Stunnel setting to change the editor.
Is there something inside of Windows which ignores the Win+I setting?

All the Windows Stunnel setup documents just say it uses the default.

In Windows, the "Edit stunnel.conf" is a program shortcut. i.e. an `.lnk`
file.

Just edit the program shortcut to change the text editor program file path
to other than Notepad.

In Start Menu, right-click on the menu item and choose Properties.
