Upgrading to Windows 10 Pro failed without Properly reverting to Windows 7. What Now?

In upgrading one of our workstations to Windows 10 Pro, the upgrade failed and did not properly revert and restore Windows 7. Because of some of the programs installed, I am looking for a suggest as to restore the operating system without loosing the existing programs and data.

I am able to boot up from the Windows 7 repair disk.

when booting from repair disk, try to use "System restore"
from "System recovery Options"

I tried several items and nothing worked. My final solution was to format the drive and install Win 10 as new.

Not what I wanted because I lost the installed programs. On the positive, at least the drive has been cleaned.
