Vista - How do I distinguish between 32 & 64-bit vista?

Vista 32 & 64 both report the same OS version.

Existing code that worked for previous Microsoft OS:
// Get the version information
Version vs = os.Version;
PlatformID p = os.Platform;
case System.PlatformID.Win32NT:
switch(vs.Major)
{
case 5:
if (vs.Minor == 0)
return "Windows 2000 " + os.Version.ToString();
else if (vs.Minor == 1)
return "Windows XP " + os.Version.ToString();
else if (vs.Minor == 2)
return "Windows XP 64 " + os.Version.ToString();
else
return "Unknown Windows NT: " + os.Version.ToString();
case 6:
if (vs.Minor == 0)
return "Windows Vista " + os.Version.ToString();
else
return "Windows Vista 64 " + os.Version.ToString();
// assumption for now
default:
return ("Win32NT family:" + vs.Major.ToString() + "." +
vs.Minor.ToString() + " ->" + os.VersionString);

Vista 32 & 64 both report the same version.

Would this work?

Console.WriteLine("This is a {0}-bit OS.", IntPtr.Size * 8);
