UAC is the option where a program will ask permission before doing a task that is potentially dangerous. You may want to change how users are prompted.

• navigate the security policy editor (secpol.msc)
• local policies
• security options
• user account controls: behavior of the elevation prompt for standard users
• choose "auto deny elevation requests" when you don't want that user to be able to do something dangerous.
• choose "prompt for credentials" when you want the user to type in the administers password when doing something dangerous.
