Примеры:
pnputil.exe -a a:\usbcam\USBCAM.INF -> Добавляет пакет, указанный USBCAM.INF
pnputil.exe -a c:\drivers\*.inf     -> Добавляет все пакеты в c:\drivers\
pnputil.exe -i -a a:\usbcam\USBCAM.INF -> Установка пакета драйверов
pnputil.exe -e                           -> Перечисляет все сторонние пакеты
pnputil.exe -d oem0.inf                  -> Удаляет пакет oem0.inf
pnputil.exe -f -d oem0.inf               -> Принуждает удалить пакет oem0.inf
pnputil.exe -?                           -> Выводит эту справку
