Как работать НЕ поднятый в Vista (.NET)

От: http://go.microsoft.com/fwlink/?LinkId=81232

А часто задавал вопрос, то, как запустить неподнятое приложение от поднятого процесса, или более существенно, как я запускаю процесс с помощью своего неподнятого маркера однажды поднятое выполнение I’m. С тех пор нет никакого прямого способа сделать это, ситуации можно обычно избегать путем запуска исходного приложения как типичного пользователя и только подъема тех частей приложения, которые требуют административных прав. Таким образом, там всегда является неподнятый процесс, который может использоваться для запуска дополнительных приложений, поскольку в настоящее время входил в систему настольный пользователь. Иногда, однако, поднятый процесс должен получить другое приложение, работающее неподнятый. Это может быть выполнено при помощи планировщика задач в Windows Vista. Поднятый процесс может зарегистрировать задачу работать, поскольку в настоящее время входил в систему настольный пользователь.

Вот пример того, как запланировать неподнятый процесс (снова из той же ссылки)
