Change Windows Administrator password in Ubuntu Live Disc
Whatever your reason for changing any users password, this simple howto will surely satisfy that need. The only way to prevent this currently is with full disk encryption. Here is how you change windows password within Ubuntu.(Other distro’s may have this nifty app in their repos as well)
You can either use your livecd or hdd.
sudo apt-get install chntpw
Now its installed, so lets get to work…
Ok I am assuming your using a Ubuntu livecd or a Ubuntu full install. You will now need to mount the windows partition read/write permission then navigate to %systemroot%/system32/config
Once your located in the config directory issue this command to change the password
chntpw -u administrator SAM
- Prompt for password for ‘administrator’, if found (otherwise do nothing) use * to blank
Now reboot and login to windows
