C ++ WMI Получить AccountName, зная SID пользователя

Как MSDN Документация утверждает, что Win32_SID Класс WMI не может быть перечислен.

Таким образом, вы не можете использовать метод ExecQuery, вместо этого используйте IWbemServices::GetObject Функция, передающая правильный WMI object path. что-то вроде Win32_SID.SID='S-1-5-82-1036420768-1044797643-1061213386-2937092688-4282445334'
