@sgunhouse Windows 10 64-bit. By the way, I'm using the Classic Start Menu (http://www.classicshell.net/). Opera 76.0.4017.107. Maybe there's a registry key involved.

I see the same behaviour with Acrobat Reader, but not with any other application.

How can I stop Opera continually putting a shortcut in the root of the programs folder of my start menu?

I have moved the shortcut to a subfolder of the program menu, and don't want a copy in the root of the menu.

I've deleted the root copy. When it reappeared, I set its hidden and readonly attributes. But it regularly reappears, with those attributes unset.

How to get rid of this permanently? Thank you.
