No, the product key on the bottom of your laptop is for Windows. You
only get one free trial period to use the Office 2007 trial software.
You cannot reinstall the trial software to extend the trial period. If
you want to keep using Office 2007 after the trial period expires, you
need to buy it. You will probably save a few dollars if you purchase
Office 2007 from your favorite online or conventional retailer versus
doing the online conversion of the Office 2007 trial software via the
Microsoft website.
