To reset your Windows password is very easy, as easy as resetting your ubuntu password. What you need is bootable Ubuntu system (ie. USB, CD or anything) and software called chntpw.
This is step-by-step to reset your Windows password:
  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 ManagerSettingsRepositoriesUbuntu Software and check the "Software restricted by copyright or legal issues" checkbox. And don't forget to reload synaptic.

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

    sudo apt-get install chntpw

  2. Resetting Windows password


    • Mount your "Windows installed" device It's 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 I've created before.

    • Goto your Windows system configuration folder Located at [WINDOWS_DEVICE]/WINDOWS/system32/config/:
      cd /media/WINDOWS/WINDOWS/system32/config/


  3. Cracking the SAM file There a SAM file on Windows system configuration folder. That's the file we're looking for. Let's crack it :) (sounds cool)
