User Account Protection (UAP) is a new security feature of Windows Vista. The point is to "force" users to work in a standard user account mode (not in administrator mode). So this technology is to allow all users to run applications and work standards work, and limiting administrator-level access only to process that requires administrator permission. So no matter what user account we use, a standard user or administrator, we still will be watched. And will be asked for confirmation when we run an operation or program that is considered dangerous.
In Windows XP there are two levels of users, namely user and administrator standards. Users run the application with standard user account and is part of the group of users, while administrators run the program with an administrator account and a group of administrators. When a user runs the program / application, the following token access administrative level privilege. The same rules, applies also to the ordinary user. As a normal user running the application, he will get a token and the privilege was limited to / in accordance with user-level course.
In windows vista, applications will be paired with a standard token or administrator token. If the application can not be identified as administrative applications, windows vista will run it as a standard application by default! If you find that an application can be run, windows vista will ask for confirmation of the user, whether to allow or not.
So the confirmation will still be displayed, even if we are included in the administrator group. This is because the default user that runs the standard users. So by default would be treated as a standard user, until the moment we needed the windows vista be an administrator to confirm the use of a program
