Many laptops come with a trial of Office, that could be it. Just to to Add/Remove programs and you should see it to uninstall or simply ignore or delete the shortcuts.
If I remember rightly they list themselves as 1 group program Microsoft Office Home and Student. Clicking on them gives either 'Program failed to start' and I think no response for the other one. Office Anytime Upgrade is also there which seemed to indicate it will open up everything
