What is User Account Control (UAC) in Microsoft Windows operating systems ?
This article applies to:
User Account Control (UAC) is a security component in Windows Vista and Windows 7 operating systems. UAC enables users to perform common tasks as non-administrators and as administrators without having to switch users, log off, or use Run As.
Installing and Running a Program with UAC EnabledSince installing some applications on a system requires an administrator access token, a mechanism is in place within the operating system to automatically detect the launch of a setup installer. When an application setup is detected, UAC displays an consent prompt for the user to validate the installation process. Following installation, the application will not require the user to provide consent or credentials, unless it is an administrative application.
Consent PromptThe consent prompt is presented when a user attempts to perform a task that requires a user administrative access.
'Windows needs your your permission to continue. If you started this action, continue'
