Sample Code:

Here's something that worked for me, the 0,0 for the service pack is what they used at MSN...

using System;
using System.Collections.Generic;
using System.Text;
using System.Runtime.InteropServices;

namespace System_Info
{
     class Program
     {
     [DllImport("kernel32.dll", SetLastError = false)]
     static extern bool GetProductInfo(
          int dwOSMajorVersion,
          int dwOSMinorVersion,
          int dwSpMajorVersion,
          int dwSpMinorVersion,
          out int pdwReturnedProductType);  

int ProductNum;

     static void Main(string[] args)
     {

         int ProductNum;  

GetProductInfo(

System.Environment.OSVersion.Version.Major,
System.Environment.OSVersion.Version.Minor,
0,
0,
out ProductNum);

         GetProductInfo(
          Environment.OSVersion.Version.Major,
          Environment.OSVersion.Version.Minor,
          0,
          0,
          out ProductNum);

Console.WriteLine(ProductNum);

         Console.WriteLine(Environment.OSVersion.Version.Build);
         Console.WriteLine(Environment.OSVersion.Version.Major);
         Console.WriteLine(Environment.OSVersion.Version.MajorRevision);
         Console.WriteLine(Environment.OSVersion.Version.Minor);
         Console.WriteLine(Environment.OSVersion.Version.MinorRevision);
         Console.WriteLine(Environment.OSVersion.Version.Revision);

         Console.WriteLine(ProductNum);

         Console.ReadKey();
     }
     }
}
