User Account Protection

Windows Vista changes the traditional Windows privilege model to help prevent users from running programs that attempt to perform operations that the user doesn't really intend or authorize. To that end, User Account Protection (formerly called Least-privileged User Account, or LUA) enables users to run at low privilege most of the time, while being able to easily run applications requiring more privilege as necessary. There are two key things to consider when building applications to make use of User Account Protection (UAP): the privilege specification model and the standard UAP execution model.
