How do I put restrictions on a windows desktop administrator account?

We at AGVsport have multiple desktops with only admin accounts. We want to make it so users cannot add new icons or alter any of the desktop settings such as the display screen, what items are on the tool bar. Creating non admin accounts would easily allow this but our organization does not want to do that. Users can have the ability to undo these restrictions since they are on the admin account, we just need to know how to get these restrictions in place
