User Account Control
About This Video
User Account Control (UAC) was introduced in Windows Vista to help increase security and improve total cost of ownership by enabling the operating system to be deployed without administrative privileges. See how Windows 7 continues the investment in UAC with changes that enhance the user experience and put users in greater control of their prompting experience. For example, the number of operating system applications and tasks that require elevation is reduced, so standard users can do more than before and will see fewer elevation prompts.
