My wife's computer and mine were running W7 OEM before we did the free conversion to W10. I have had several OEMs but never a retail... I have run the script that identifies our installations and in both cases it describes them as "RETAIL"... Does that mean that next time I build a computer I can install the W10s as retail ? If I simply move the system with macrium images and fix the drivers, will they fire up as authorized ?
