kiosk mode - Windows 7

Our Client has been testing one of the course revised versions of Flash to HTML5 conversion and they have some questions.

They are running Windows 7 Professional on their machines and have been having some difficulty in getting the browsers (Edge or Chrome) to startup in "kiosk mode" when the program is launched. They have found instructions for Win 8.1 and Win 10 but they are evidently not effective on Win 7.

Do you have any suggestions for getting either of these browsers to launch in "kiosk mode" when first started and they do not want the visitors to see any toolbars or have any options to force the program to quit or access any other web pages or sites, and only want them to be able to interact with the html-5 file as constructed.
