B: You can configure Administrative Template policy settings to one of three states: Not Configured, Enabled, and Disabled. Not Configured is the default state for all policy settings. Policy settings set to Not Configured do not affect users or computers. Enabling an Administrative Template policy setting activates the policy setting. When Enabled, the action described in the title of the policy setting applies to the user or computer. When Disabled, the opposite action described in the title of the policy setting applies to the user or computer. Usually Not Configured and Disabled policy settings produce the same results. The difference is that Not Configured policy settings do not apply to the user, but Disabled policy settings apply to a user.
