Use the Win32 API function "GetVersionEx".  It will fill in a struct with all the info you need.  Here is how to use it:
     http://msdn.microsoft.com/library/en-us/sysinfo/base/getversionex.asp

Here is a wrapper class that I use:
      class CVersion : public OSVERSIONINFO
      {
      // Construction
      public:  
            CVersion()
            {
                  dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
                  _CTL_DEBUG_FAIL( ::GetVersionEx(this) );
            }
      };


Hope that helps,

Actually, you don't have my debugging library, so that won't help you.  Use this instead:

     class CWindowsVersion : public OSVERSIONINFO
     {
     // Construction
     public:  
          CWindowsVersion()
          {
               dwOSVersionInfoSize = sizeof(OSVERSIONINFO);
               ::GetVersionEx( this );
          }
     };
