Hello ECWilkins,
Full Versions of Office do not, normally, come standard on computers. Computer Manufacturers will often include a Trial version of Office, which allows you to use it for a limited number of uses, but if you wish to continue using it, you would need to by a Full Version of Office.
If the copy of Office, that came with your computer, is supposed to be a Full Version, then the Product key would be included in the documentation that came with the computer. If you are unable to find the Office Product Key and you still believe that the computer should have come with a Full Version of Office, please contact the Person, Company, and/or the Computer Manufacturer, that you bought the computer from, for further assistance.
If you would like to buy Office, please see this page: http://office.microsoft.com/en-us/products/FX101211561033.aspx
Thank you,
