Did you lose your windows password? Are you looking for solution for this? This tutorial will teach you how to reset or break windows7 Administrator password.

Follow the steps to Recover or Break Windows7 Administrator Password

1. Download chntpw tool

• To Create Recovery USB Disk you need to download chntpw tool. Get it from here. http://pogostick.net/~pnh/ntpasswd/usb110511.zip

2. Create your USB Windows Password Recovery Disk Bootable.

• To create USB extract above downloaded file in your USB root directory
• Don't forget to backup your USB data elsewhere before extracting and using it.
• Now run Command Prompt (cmd.exe) as administrator.
• Locate your USB disk drive.
• Now run command exact like here. J:\syslinux.exe -ma J:  (here J: is drive letter of my USB drive, replace it as your drive letter).

3.  Boot USB into Locked Computer.

• Now your USB is ready to use. Plugin into locked computer and restart.
• At boot screen immediately press boot menu key. (For me it's F9) OR another way is to set USB as first boot in BIOS Settings.

4.  Reset/Break Win7 Administrator Password.

• After booting from USB you see that chntpw tool is started. At the first screen it shows you Copy right information, Driver info. and many things. Don't press any key,just leave it.
• On successfully booting it automatically detects your Hard drive partitions and prints a list of your partiotions.
• Now find partition in which you have installed win7. For ease it also prints BOOT beside of that partition. (Use it if you are confused :) )
• Press a number key which is associated with your bootable win partition and press ENTER.
• After few seconds, next screen asks you for enter registry path, but don't do anything just press enter.
• In the next menu select 1 for Password Reset [ SAM System Security].
• Next screen will shows you three options, First will "Edit User Data and Passwords.", to select this press 1 and then Enter.
• In this Menu again there will be 3-4 options, but you have to select 1st. It will "Clear (Blank) Password." 
• Now if successful then it says "Password Cleared".
• Then press ! and ENTER to quit.
• At next it asks to write SAM, press y and enter.
• Now again hit q to quit.
• Reboot your Computer. Whoa !!! Password removed.

I have tried it on my Windows7 and it's working, but not tried on XP. If you have XP on your machine then try it and post result in comments. ( I am sure it will work.)

Enjoy!
