How to uninstall drag & drop extension

Couldn't find the option in the Winscp app. Couldnt find a how to on the forum search or via google.
How do I uninstall this extension, I do not want it.

It is uninstalled with WinSCP.

Or do you want to keep WinSCP, just uninstall the extension?
The easiest way to do that is to uninstall WinSCP, keeping your settings.
And then reinstall WinSCP without the "extension" components:

I'm pritty sure that I unchecked that when I installed win scp but I will try again.
