Prevent people interfering with laptop when running a video

Hi all

My wedding anniversary soon and, at a party, I want to run a DVD of our wedding ceremony on my (win 7) laptop so that guests can view it ...

Two questions:

1. How can I set it to run on continuous loop?
2. How do I disable guests being able to use the laptop - to prevent guests (or their pesky kids ) tinkering with, changing or reading info stored the laptop? Specifically I guess prevent them from using the keyboard or mouse...but open to ideas...

Thanks...

No thoughts, anyone?

Connect your laptop to a television and lock the laptop up that simple

That was my only conclusion as well... probably the simplest way. Ta.

Most Welcome
