the microsoft support site will have all that information available

Also, iirc, the particulars on how to do that were displayed as part of the upgrade installation process and is probably on your hard drive already.

Hi Chris, I'm puzzled by your "...none of my recovery media will work." Could you perhaps explain with a little more detail? What recovery media? Windows 10 is better than Windows 8.1 for many reasons. For example, I have a 14 year old DELL notebook running fine with Windows 10.
