How can I tell if my netbook is a Home Edition?

I got a Dell Netbook for Christmas and I don't know if it has Home Edition. It says Dell Starter when I turn it on, but it also has Microsoft Word and Movie Maker and pretty much all the same features that my laptop had. I'm told that netbooks don't come with all of that, you have to buy/Download the Home Edition it. But since mine has it all, does that mean it already has Home Edition? How can I tell?
