I have laptop and on it windows XP professional operating system. I gave yesterday to my sister this computer, and this morning I have seen that she deleted my admin account. Now I can log only as a guest and cant access to some very important files. I have heard that I can reset my account and password with Knoppix linux distribution. Would you be so kind and explain me how?

After booting Knoppix, open shell and type following command:
cat /etc/fstab
Then type:
mount -o rw /dev/hda2 /mnt/hda2
and then:
mount -o rw /dev/sda1 /mnt/sda1
Now type:
cd /mnt/hda2/WINNT/system32/config
and then
ls -l
After that, type:
Chntpw
And then:
chntpw -l sam system security
Now, you will able to see all accounts. Youll see that one is disabled. Change -l for -u username (enter wanted username), after that youll be asked for password you can enter it or not, and thats it. After youve done all of this, reboot your computer and normally log in to windows. I hope I help you.
