Windows 10 upgrade aborts

Last Modified: 2020-02-07
I am upgrading 10 computers from Windows 7 Pro to Windows 10 Pro with the free upgrade offered by Microsoft.  I have one system that just when it is doing the last installation of updates it starts "undoing changes to the computer".  It comes up with and error when you log back in to Windows 7 of Ox8007042B - Ox 3000D and then when you select the details button it says " FIRST-BOOT PHASE ERROR Migrate Data Operation.  Go to Microsoft.com/fwlink/?linkid=528892"  I tried going to this address and I also searched it and the solution was to purchase an analyzer program for $29.95 which comes up with Malware errors.  When I run another Malware checker I come up with no problems.  Any ideas would could be stopping the upgrade?  I have disabled everything in the startup in msconfig and I have cleared all temp folders and it still cannot finish the upgrade.
