I was looking for a way to determine the above. I could not really find it easily and google somehow couldn't help me much with it too.

Thanks.

You need the GetNativeSystemInfo() API Call. The information you are looking for will be returned in the SYSTEM_INFO structure in the wProcessorArchitecture member.
