How do I get rid of the second instance of Skype on my Windows 10? [View all]

Ever since a recent Windows update, I've been noticing that there's a second Skype running in the background of my Windows 10 Pro system. Looking at the running tasks, there's the usual, green logged-in icon of my desktop Skype, but also a grey, "Skype - not signed in" that's just sitting there not apparently doing anything. I can quit the process without ill effects.

But I don't want it there in the first place.

Googling the problem identifies the reason (installing Desktop Skype) and confirms that a lot of people have noticed this, but not how to get rid of it.

The control panel's "programs & features" only lists the Desktop version I installed, but neither here, nor in "Windows Features" do I find this other Skype.

Any suggestions on how to get rid of this unwanted passenger on my laptop?
