Okay, I recently did a clean install after a virus affected my firewall and there was no way around needing to new Windows 7. So, I got a new Windows 7 Home Premium (Service Pack 1). There is one problem; I need a product key, which I don't have because I did a clean install as my Windows disc is gone and I can't find it anywhere. And after 30 days (from when I reinstalled it (7/10/12)), I don't know what's going to happen.
So, how can I get a product key?
