How could I find my Microsoft word product key through the program itself?

Idealist Dreamer Realist: How could I find my Microsoft word product key through the program itself?
I need to reinstall windows. The issue is that I want to keep my microsoft word and be able to have it when I reinstall windows. But I do not have my Microsoft word product key on me. Is there a way to view my key through microsoft word itself? My laptop came with a trial version and I got the product key from a friend.
