I can't get into the Windows store to access the free download for 8.1. I then spent 40+ minutes on the phone with Microsoft support who then sent me a link to download 8.1 using the product key only.
However, my Windows 8 came installed with my computer, so how do I find a product key for my Windows 8 in order to do the upgrade?
I tried to call back to support but they were shut down for the day.
Thanks!
