Changes in User Account Control

Updated: March 9, 2008

Applies To: Windows 7, Windows Server 2008 R2

This product evaluation article written for the IT professional describes the changes for User Account Control (UAC) in Windows 7 and Windows Server 2008 R2.

The improvements to UAC in Windows 7 and Windows Server 2008 R2 result in an improved user experience when configuring and troubleshooting your computer. Improvements in UAC functionality include:

  • Increase the number of tasks that the standard user can perform that do not prompt for administrator approval.

  • Allow a user with administrator privileges to configure the UAC experience in the Control Panel.

  • Provide additional local security policies that enable a local administrator to change the behavior of the UAC messages for local administrators in Admin Approval Mode.

  • Provide additional local security policies that enable a local administrator to change the behavior of the UAC messages for standard users.

For more information about these improvements, see What's New in User Account Control. For information about configuring UAC, see User Account Control Step-by-Step Guide.

The default UAC setting allows a standard user to perform the following tasks without receiving a UAC prompt:

  • Install updates from Windows Update.

  • Install drivers from Windows Update or included with the operating system.

  • View Windows settings. (However, a standard user is prompted for elevated privileges when changing Windows settings.)

  • Pair Bluetooth devices to the computer.

  • Reset the network adapter and perform other network diagnostic and repair tasks.

The following table lists the likelihood of UAC prompts for user actions in comparison to Windows Vista SP1.
