Hi Felicias baby boy,
The Product Key on the bottom of your computer is only for Windows. Computer Manufacturers (such as Dell) will often include a Trial version of Office in the computers they sell. The Trial version of Office will work for a while, but to continue to use Office, you would need to buy a Full Version.
If you believe you were supposed to receive a full version of Office, with your computer, please contact Dell for futher assistance.
Thank you,
