Like mhelm1 suggests, you'll need an email client to read emails and their attachments, if you don't already have one (do you?). Hotmail is free and easy to use. Just open it up in Internet Explorer and enter in your Yahoo, Gmail, Live ID, or whatever email account info you use - http://explore.live.com/windows-live-hotmail
Then you'll be ready to receive emails and open attachments.
