Convert to the Full version of Microsoft Office

To convert your Trial or Subscription version of Microsoft Office into the corresponding Full product version, you must enter a Product Key obtained from a Full product version of the same edition of Office. For example, if your Trial version is a trial of Microsoft Office Professional 2010, when you convert to the Full version you must enter a Product Key for Microsoft Office Professional 2010, not for, say, Microsoft Office Standard 2010. Converting from a Trial or Subscription version to the Full product removes the usage limits on the software. None of your program settings or data is affected by the conversion.

Enter Product Key   Click this option if you have already purchased your Full product either online or from a retail store. You can usually find the Product Key either on your CD case or other packaging, or in the confirmation e-mail message from your online purchase.

Buy Product Key Online   Click this option if you have not yet purchased a Full product and want to buy the product now on the Internet. Your Web browser opens at a site where you can make your purchase and obtain the Product Key for your copy of the Full product. (Online purchase of a Product Key may not be available in some countries/regions.)
