User Account Control

= Overview =

UAC (User Account Control) is a security feature enabled on all post-XP (Vista, 2008, 7) systems that, for UAC compliant applications, throws a "prompt" to elevate permissions to Administrative levels for anyone performing an administrative action. UAC is primarily intended as a Malware and Virus control solution, but can be a hinderance for testing systems where many administrative tasks must be performed.
