Hi, I bought my inspiron a few weeks before Windows 8 release. It came with Windows 7 and an option to upgrade to 8 as per http://www.dell.com/learn/us/en/19/campaigns/windows-upgrade-offer. I did upgrade and was wondering what my options are if I wanted to go back to Windows 7. I don't have the box or any of the booklets that came with the laptop anymore, so I don't have the windows 7 product key. I also didn't do any backups when upgrading. Is it possible to retrieve the original windows 7 product key by service tag? Also, if I reset the laptop to factory defaults, will it go back to Windows 7 that was originally installed on it? Thanks very much.
