Autoplay settings are now in the Windows 10 Settings themselves. Settings, Devices, Autoplay Pane. My guess is that you'll want either, Ask me every time, or, Open folder to view files (File Explorer), as your choice for the Removable Media dropdown.
My guess is that it's now set to, Take no action.

If you think that you can think about a thing, inextricably attached to something else, without thinking of the thing it is attached to, then you have a legal mind.
