Yes. And Ubuntu provides a package for this program.

All are parameters. '-e' means you want to start the program as
registry editor. Then, the rest if just the list of the hives you want
to open. SAM is mandatory, chntpw is always looking for it. Security &
software might actually not be mandatory for what we do.

You'll likely find pci#vend_XXXX&dev_XXXX keys matching your SATA buses.

It's the command for creating a 'new key'

It's the command for creating a 'new value' in a key.

Backup the config directory files. They are the hives containing your
Windows registry.

I unfortunately don't happen to have a VM using SATA buses, so I've no
idea what HW IDs is Qemu using for its buses. It could be interesting
to have a look though.
