Detecting Whether the Remote Desktop Services Role Is Installed

You can use the Win32_ServerFeature WMI class to detect whether the Remote Desktop Services server role is installed.

The following C# example shows a method that returns True if the Remote Desktop Services server role is installed and running or false otherwise. Because the Win32_ServerFeature WMI class is only available beginning with Windows Server 2008, this code is not compatible with earlier versions of Windows.

static void Main(string[] args)
{
    // 14 is the identifier of the Remote Desktop Services role.
    HasServerFeatureById(14);
}

static bool HasServerFeatureById(UInt32 roleId)
{
    try
    {
        ManagementClass serviceClass = new ManagementClass("Win32_ServerFeature");
        foreach (ManagementObject feature in serviceClass.GetInstances())
        {
            if ((UInt32)feature["ID"] == roleId)
            {
                return true;
            }
        }

        return false;
    }
    catch (ManagementException)
    {
        // The most likely cause of this is that this is being called from an 
        // operating system that is not a server operating system.
    }

    return false;
}
