Converting the trial version to the full version

How can I convert my trial version of Microsoft Office 2007 system to the full, released version?

Office 2007 lets you enter a valid product key to convert your trial version to a full version without reinstallation. From inside any Office 2007 application, do the following:

1. Click the Office Button in the upper left corner of the Office applications.
2. Select Options (e.g., Word Options).
3. In the resulting dialog box, select Resources.
4. Select Activate Office and follow the prompts from there. Have your product key ready.

Just so you aren't surprised, even after activating you'll see a message in the Resources section that says Activation is required to continue using all the features in this product, and the Activate button remains enabled. Ahhh… software!
