Во вложении - скомпилированная утилита, которая корректно устанавливает нужный параметр (проверено на XP и 2003). Пригодится всем, кто имеет дело с установкой драйверов - утилиту достаточно запустить перед установкой неподписанного драйвера и он установится молча, т. к. выбор политики сработает мгновенно. |
