How do I retrieve product key for Microsoft office 2007?

[Nattatat]

I had to reinstall my PC from factory settings, and Microsoft Word Home and Student 2007 is part of the OS, and previously I had purchased a product key. I need to find how to retrieve that key so I can use Microsoft Office again. Can I get it from the Microsoft website? I cannot find how to do that.
