Symptom: To change the windows administrative password by Ubuntu, if you forgot the password or to hack.

Solution:  Here is how you change windows password within Ubuntu. Install the software chntpw.

Ok I am assuming your using a livecd or a Ubuntu machine which is  full installed
You will now need to mount the windows partition read/write permission then navigate to %systemroot%/system32/config
