Fix Recommendation

Configure the policy value for Computer Configuration >> Windows Settings >> Security Settings >> Local Policies >> Security Options >> "User Account Control: Behavior of the elevation prompt for administrators in Admin Approval Mode" to "Prompt for consent on the secure desktop".

The more secure option for this setting, "Prompt for credentials on the secure desktop", would also be acceptable.
