Clarified that existing listed location is the policy location.
Added registry location as recommended by user TonyLongsonFJ
Personal note: While adding the registry location to the article is not a bad idea, it will be a lot of work to add that to all the settings in all the articles. It could also be a lot of maintenance when changes occur.
It may be better to refer in the articles to the fact that the associated registry locations for all settings can be found in the Group Policy Settings Reference downloadable spreadsheet.
