"enable automatic startup for services installed in the container"

What’s the effect of this option?The services will start when I reboot my computer?

Even though the help documentation says it will, what happens instead is it will start the next time the containment service is started which is when another file is run in containment. So it goes like this: service created in containment > reboot computer without resetting containment > run an application in containment > previously created service is started in containment along with application that is running in the container.
