Answer: User Account Control (UAC) is a security component that enables users to perform activities as non-administrators (called standard users), and as administrators without having to log off or use Run As.
When a user account is part of the Local Administrator group , in reality the user performs most tasks as a standard user. Separating the non-administrative and administrative tasks , decreases the security risk. Malicious software can exploit UAC being disabled. Malicious software can be installed without any notification
