What is UAC in Vista?
User Account Control (UAC) feature was introduced to reduce the exposure and attack surface of the operating system by requiring that all users run in standard user mode.
This limitation minimizes the ability for users to make changes that could destabilize their computers or inadvertently expose the network to viruses through undetected malware that has infected their computer.
Note: By disabling UAC, your system becomes vulnerable to attack.
