They most likely used a live windows PE cd.
You can reinstall windows, or you can use an NTFS boot disk to change the admin password. Both google accessible.
I'd just go with a reinstall, unless there is stuff on there you need. Then I'd clone the disk, reinstall and then assume rights over the drive with
the fresh install - but it's been a long time since I did that, using ghost and ghost explorer. lol, old...
it's doable, but ntfs boot disks with the ability to change the pword work in seconds...
