I tried resetting the password of windows 7 Using 'chntpw' command in Ubuntu . It showed success . But when I try to login from Windows it does not seem to be changed.

I first used live USB of ubuntu 11.10 and did ''Try Ubuntu''. Then I did

sudo apt-get install chntpw

and then

cd /media/Vista/Windows/System32/config

sudo chntpw -u username sam

.

I did according to this link . http://www.psychocats.net/ubuntucat/resetwindowspasswordold/

and got success like this.

Hives that have changed:

Name

0 Write hive files? (y/n) [n] : y 0 – OK .

But when I try to login to windows with blank password , I could not login.

I also tried changing the password and showed success but I could not login with that password . Thank you . Any help is very much appreciated.
