User Account Control: Turn on Admin Approval Mode
Applies To: Windows Server 2008 R2
The User Account Control: Turn on Admin Approval Mode policy setting controls the behavior of all User Account Control (UAC) policy settings for the computer. If you change this policy setting, you must restart your computer.
The options are:
Enabled. (Default) Admin Approval Mode is enabled. This policy must be enabled and related UAC policy settings must also be set appropriately to allow the built-in Administrator account and all other users who are members of the Administrators group to run in Admin Approval Mode.
Disabled. Admin Approval Mode and all related UAC policy settings are disabled.
If this policy setting is disabled, the Security Center notifies you that the overall security of the operating system has been reduced.
