How do I change Windows 7 starter to a regular Windows 7?
 

I am not that computer Windows 7 Pro Product Key savvy, so I do not know Windows 7 Ultimate much. I was just wondering what Office 2007 Pro Plus is and how it is better than Office 2007 Product Key. I managed to download a tool from Microsoft and it said that my computer was compatible for Windows 7. Now, how do I go about getting Office 2010 Activation? Is it free to download or do I have to buy it? If so, how much does Microsoft Office 2010 Product Key cost?
