What skin comes on Kodi 17.1?

This probably the wrong forum to post, so please correct me if necessary.

I always used the Confluence skin but do not see where the skins reside to mkae the changes,
I’m looking to update the ‘Shutdown’ screen. It used to be under \XBMC\addons\skin.confluence\720p\home.xml

I prefer to shutdown the program without going to the extra menu to touch the EXIT command.

Thank you for your assistance!
