Key: SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System
Value: "ConsentPromptBehaviorAdmin"
Type: REG_DWORD
Size: 3
Data: This MUST be a value in the following table.
0x00000000
This option SHOULD be used to allow the Consent Admin to perform an operation that requires elevation without consent or credentials.
0x00000001
This option SHOULD be used to prompt the Consent Admin to enter his or her user name and password (or another valid admin) when an operation requires elevation of privilege.
0x00000002
This option SHOULD be used to prompt the administrator in Admin Approval Mode to select either "Permit" or "Deny" an operation that requires elevation of privilege. If the Consent Admin selects Permit, the operation will continue with their highest available privilege. "Prompt for consent" removes the inconvenience of requiring that users enter their name and password to perform a privileged task.
