Hi, you'd only have done a clean install if you've booted from 10586 installation media and chosen that route. The intention was from the working state you re-established to let the update happen again, with the confidence of the disk image backups.
Please do use disk imaging.. the more programs you install, the more changes you make, the more risks you take.
Disk imaging saves time, frustration, data, and stress, as well as providing a complete backup.
