In some countries they share the use of computers, called cyber cafe. These centers are to rent the use of computers for playing games and surfing the Internet . Enabling this option you would be covering a segment of potential customers for your application.
It would be interesting to include a privilege level , which prevents delete the games by users.
Currently there is not this option in Launch Box, to prevent changes in computers I use several softwares, ToolWiz Time Freeze and Deepfreeze for this.
Sincerely,
