This collection contains links to detailed information about User Account Control (UAC) for the IT professional. If you need help and how-to information for using UAC at home, see the following:

UAC is a security component that allows an administrator to enter credentials during a non-administrator's user session to perform occasional administrative tasks. UAC also can also require administrators to specifically approve administrative actions or applications before they are allowed to run.

UAC was introduced in Windows Vista. In response to customer feedback, UAC in Windows 7 implements a number of improvements, including reduced number of consent or credential prompts. For more information about UAC changes in Windows 7, see What's New in User Account Control.


Except where noted, the design of UAC is consistent between the server and client operating systems.
