First, Pre-Shared Key and Personal ARE the same.
I have read about the opposite where profiles keep returning even after you delete them and the suggestion that seemed to work for them was to first find all the profiles by SSID and delete the folders, then remove the wireless network adapter, reboot and reload the driver (note: you either need to back this up before deleting it or you may need to provide a wired connection, so the driver can be found & installed). Then create your profile and hopefully with the registry cleared, this time it sticks. Source: Striker-One's reply
