You don't have policies that force settings for the look of users' computer desktops. Each user's chosen desktop settings are applied from his or her roaming profile to any computer he or she signs in to. You think it's important for users to have this choice, but you'd like a consistent look for computers used for product demonstrations to customers. What's the best way to do this without affecting users when they sign in to other computers?

a. Configure desktop policies in the Computer Configuration node of a GPO and link this GPO to the OU containing the demonstration computers.
b. Configure loopback policy processing in Computer Configuration. Configure the desktop settings in User Configuration and link the GPO to the OU containing the demonstration computers.
c. Create a user named Demo. Configure Demo's desktop settings and use only this user account to sign in to demonstration computers.
d. Create a GPO with a startup script that configures desktop settings suitable for demonstration computers when these computers are started. Link the GPO to the OU containing the demonstration computers. Instruct users to restart demonstration computers before using them.
