Hello adamb95,
You seem to be confusing the names of two different programs, Microsoft Office and Microsoft Works.
Microsoft Office come in a version called "Home and Student" so I assume the issue you are posting about is with Microsoft Office Home and Student.
If you have a copy of Office Home and Student, the product key would be listed either on the sleeve that the Office Disks came in or on a card that came with the disks.
Please Note: New computers often come with a Trial version of Microsoft Office. If you did not specifically ask to have a Full version of Office included in your new PC (and pay extra for it), then it is likely that the copy of Office installed
on the PC is a Trial version.
Thank you,
Darin MS
