Hi so I have a friends computer who got hacked from a phone scam and they enabled the syskey so it pops up once the computer starts.  I followed these instruction on how to fix it: 

https://www.top-password.com/knowledge/remove-syskey-startup-password.html

But now all the computer does is goes in a repair loop once it starts. I then followed instructions how to get it out of the loops and at one point it gets to the windows registry Hive. I noted all the values in the Hive are Zero here so it stated the repair would not work. I do have a copy of the back up Hive with normal values I just don't know how from the Windows command prompt in Windows 10 how to copy them back to Windows/system32/confg to try and get this computer to start properly. I have attached on the link below the picture of the Hive files and the location of the back up. Any help would be greatly appreciated.

It can be done with a command prompt and a Windows 10 install disk but the easiest way would be using the copy and paste command using a Windows PE disk. I am not sure if there will be a read/write problem because of Fast Startup in Windows 10 which enables a hibernation file.

Burn the iso file to a DVD or use Rufus to create a bootable flash drive. Once on the desktop you can copy the hives from a USB flash drive to the config folder.

Using a Windows 10 install disk you can access a command prompt at the language screen by pressing Shift + F10 or by selecting Repair Computer > Troubleshoot. You can then use the command prompt to copy files from the USB flash drive to config.
