Я протестировал этот скрипт с IE10 на Windows 8, и автор проверил его с Internet Explorer 11 на Windows 8.1, но я думаю, что он должен работать и с предыдущими версиями ... Он был скопирован отсюда
помните, что после выполнения сценария Internet Explorer должен быть перезапущен.

# Explicit Proxy Disabled and automatically detect proxy set to ON
# Explicit proxy Enabled and automatically detect proxy set to OFF
#provide your proxy here
