Reset Windows admin password without knowing the old password.

is a simple tutorial on resetting the admin account password of
any Windows Operating System.  All you will require for this is one
Ubuntu live CD.

  1. Insert Ubuntu Live CD and boot from it.

  2. Open terminal and install chntpw in Ubuntu. To do so use the following commands.

    sudo apt-get update

    sudo apt-get install chntpw

  3. Now mount your Windows volume. In my case it was dev/sda1. Replace it with yours.

    sudo mkdir /media/WINDOWS

    sudo mount /dev/sda1 /media/WINDOWS

  4. Now navigate to the Windows configuration folder.

    cd /media/WINDOWS/WINDOWS/system32/config/

  5. To reset the administrator password enter

    sudo chntpw SAM

  6. After completing this command you will see 5 different choices. Select the 1st one and press Enter and done.
