{
    // Get OperatingSystem information from the system namespace.
    System.OperatingSystem osInfo = System.Environment.OSVersion;
 
    // Determine the platform.
    if (osInfo.Platform == System.PlatformID.Win32Windows)
    {
        // Platform is Windows 95, Windows 98, Windows 98 Second Edition, or Windows Me.
        switch (osInfo.Version.Minor)
        {
            case 0:
                //Console.WriteLine("Windows 95");
                return WindowsVersions.Win95;
 
            case 10:
                //if (osInfo.Version.Revision.ToString() == "2222A")
                //    Console.WriteLine("Windows 98 Second Edition");
                //else
                //    Console.WriteLine("Windows 98");

                //Console.WriteLine("Windows Me");
                return WindowsVersions.WinMe;
        }
    }

    {
        // Platform is Windows NT 3.51, Windows NT 4.0, Windows 2000, or Windows XP.
        switch (osInfo.Version.Major)
        {
            case 3:
            case 4:

                //Console.WriteLine("Windows NT 4.0");  // = 4
                return WindowsVersions.WinNT3or4;
 
            case 5:

                    case 0:
                        //name = "Windows 2000";
                        return WindowsVersions.Win2000;

  2. You comments 'Windows Vista or Windows Server 2008 (distinct by product type)' mean you should get the ProductType not using Pinvoke and OSVERSIONINFOEX!? Where is that ProductType in .NET Version prop?
    Thanx.
