We had a situation where we wanted to setup an Intuit QuickBooks POS system in a locked down configuration so that it was more like a kiosk for the register attendants. There are several ways to go about this but most will lock down every user, but in our case we only wanted to affect the POS users to prevent unnecessary changes to the system.
The process we came up with uses a combination of parental rights, registry hacks, and user menu modifications. You will also need to make sure you create a special local user account that you will assign these changes to. Before attempting this process, make sure you have a backup of your system in the event something doesn't work as expected.
