Permission to run specific programs

Permission to run specific programs

"I have a XP Service pack 2 installed on my homne machine. I have admin access to this machine but I want to run most of my programs as non admin user.
How can I do this?
I know I need to create a new account, what rights should I grant that account?
How do I make sure apps like Adobe photoshop, Itunes are accessible to this newly created account"
