Any Win 32 API or WMI class to read User Accoutn Control configured values?

Can the configured values of User Account Control Group policy Security settings on Vista and later, be read programmatically using a Win 32 API or a WMI class? If yes, do let me know the API\Class

I've already tried reading the registry values (that store the values of these settings - located under <HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\policies\system>) Now I'm looking out for a way to read these settings without using the Windows registry values directly

See here.
