This policy setting controls whether the elevation request prompt is displayed on the interactive user's desktop or the secure desktop.
The options are:
* Enabled: (Default) All elevation requests go to the secure desktop regardless of prompt behavior policy settings for administrators and standard users.
* Disabled: All elevation requests go to the interactive user's desktop. Prompt behavior policy settings for administrators and standard users are used.
Countermeasure:
Enable the User Account Control: Switch to the secure desktop when prompting for elevation setting. The secure desktop helps protect against input and out spoofing by presenting the credentials dialog box in a protected section of memory which only is accessible by trusted system processes.
Potential Impact:
None. This is the default configuration.
