Any help? I use WinXP SP2 and VS2005

string query = "select * from Win32_OperatingSystem";

ManagementObjectSearcher searcher = 
  new ManagementObjectSearcher(ConfigNamespace, query);

ManagementObjectCollection collection = searcher.Get();

foreach (ManagementObject item in collection)
{
  //PropertyData pd = item.Properties["MUILanguages"];

  foreach (PropertyData data in item.Properties)
  {

  }
}
