Configure Student Training Accounts

[john john mackey]

I am prepaing to teach 4-6 students (work peers, collegues) on Windows Vista laptops, not networked, with a common account name (Student) and a common password. I have set them up as Standard Accounts so that they don't have administrative privileges. I have also decided to use the Parental Control feature to turn OFF game playing. What I also want to do is BLOCK only one program from the user, a proprietary application that resides on the laptops I have for training. Is there a simple way to block my one specific program from the "Student" account? Thank you. John John Mackey
