Windows Vista User Account Controls

Windows Vista User Account Controls

User Account Control (UAC) is a technology and security infrastructure first introduced by Microsoft in the Windows Vista operating system.

It aims to improve the security of Microsoft Windows by limiting application software to standard user privileges until an administrator authorizes an increase in privilege level.

In this way, only applications that the user trusts receive higher privileges, and malware is kept from receiving the privileges necessary to compromise the operating system.

In other words, a user account may have administrator privileges assigned to it, but applications that the user runs do not also have those privileges unless they are approved beforehand or the user explicitly authorizes it to have higher privileges.
