When I bought my laptop back in '07 it came with a Home and Office trail key. After 3 months of using it I finally decide it to get the full version. Then one day my husband saw that my laptop was runing a little slow. So he went on and erase some programs including my home and office. Now I want to get it back but i can't find my product key. I know that I need a new one I just don't know how to get it. Can you please help?
