    How to reset your Windows password using Ubuntu

    Resetting your Windows password is as easy as resetting your Ubuntu password. What you need is a bootable Ubuntu system (ie. USB, CD or anything) and software called chntpw

    Please find the steps o reset your Windows password below.

    1. # Boot from your bootable device (Ubuntu Live Session)

    Shutdown your computer and boot up using your bootable system. So you run Ubuntu on Live Session that means you run your system without install it!

    2. # Set your repository

    Goto Synaptic Package Manager -> Settings -> Repositories -> Ubuntu Software and check the ďSoftware restricted by copyright or legal issuesĒ checkbox. And donít forget to reload synaptic.



    3. # Install CHNTPW

    Install from Synaptic Package Manager or use this command on shell:

    sudo apt-get install chntpw
    4. # Resetting Windows password

    # Mount your ďWindows installedĒ device

    Itís depending on your system, example:

    sudo mkdir /media/WINDOWS
    sudo mount /dev/sda1 /media/WINDOWS
    On my system Windows installed on /dev/sda1 and I want to mount it to /media/WINDOWS that Iíve created before.

    # Goto your Windows system configuration folder

    Located at [WINDOWS_DEVICE]/WINDOWS/system32/config/:

    cd /media/WINDOWS/WINDOWS/system32/config/
    # Cracking the SAM file

    There a SAM file on Windows system configuration folder. Thatís the file weíre looking for. Letís crack it

    chntpw SAM
    And if you see the output similar with image below, itís mean you can crack the SAM file.



    As you see, there are 5 choices. Just type ď1″ and press ďENTERĒ to reset your password.

    Note: Iíve try this on my system and work well! But Iíve never try another choices (2-4) yet, you can try yourself.
