Activate Microsoft Office 2010 in Office Starter
Major manufacturers of personal computers have pre-loaded Microsoft Office 2010 on new computers, ready to use after you purchase and activate it. To activate the software you either already purchased Office 2010 when you bought your computer from the manufacturer, or you can purchase a Product Key Card for Office 2010.
In either case, your purchase provides you with a Product Key that unlocks Office 2010. Product activation is the process of supplying and verifying your Product Key.
You might already be using Microsoft Office Starter 2010, which is also pre-loaded on your computer. After you purchase Office 2010 you can activate it within an Office Starter program.
In Word Starter or Excel Starter, on the Home tab, click Purchase , and then click Activate Microsoft Office.
When you are prompted to close all Office Starter programs, do so, and then return to the prompt and click OK.
If you are prompted to allow the program to make changes to your computer, click Yes.
Enter the product key for your copy of Office 2010. If you need help finding your product key, click Learn more about Product Keys and see examples.
