security - Silently Skip Windows 7 UAC Prompts?

NOTE: I am not trying to disable UAC.

I have a Windows 7 machine where I've added one administrator account and one regular user account. When using the regular user account, a UAC dialog will show up having a password prompt when an application requires administrative privileges. Entering the administrator's password will allow the action to continue, but this is not the behavior that I require. Instead of prompting for the password, I would like the action to either silently fail (with the action logged in the system log) or show a permission denied dialog.

Is this possible? If so, how do I do it?

Answer

You can change how UAC acts in this scenario by using Security Policies:

Instructions from here:

Follow these steps to eliminate UAC prompts for standard users:

• Click on the start menu, type "secpol.msc" and hit Enter.


• When the "Local Security Policy" editor ("snap-in") opens, double-click on "Local Policies" -for those affecting this particular
  machine- and double-click on "Security Options".


• Scroll down until you see a node labeled "User Account Control: Behavior of the Elevation Prompt for Standard Users" (careful, another
  policy starts with the same name, but actually affects computer
  administrators!) Double-click on it and the following dialog will
  open:

• The default behavior for standard users, selected in the dropdown menu pictured above, is "Prompt for credentials": whenever elevated
  privileges are required, they'll need to select an administrator and
  enter its password in a UAC prompt to proceed with the action.


• Click on the dropdown, and select the "Automatically deny elevation requests" option instead; click "OK" to apply the new setting: from
  this point on, standard users won't event get a UAC prompt when they
  attempt any task that needs administrative permissions.
