Cracking Windows XP

Cracking Windows means 2 things
1>cracking the password without knowing the original password
2>Somehow Knowing the password and then using that password without letting the user know

cracking password
In XP we generally deal with 2 types of account.
Administrator Account
User Account

When XP is loaded in a computer,it asks for administrator password,generally people keep   it blank(So that  pasword can be reset when we forget later and Most of the time,people dont use their Administrator account,they like to work with   their user account.

This is how you can  crack their PC and hack Administrator Password
  1. Start your computer 
  2. It will take you to logon screen.where only user Account is visible, 
  3. Press Alt+Ctrl+Delete (2 times).it will take you to old NT style logon box 
  4. On username:  administrator   
  5. Password:                    press Enter     
  6. System will login using administrator account.
  7. Now from ur Administrator account,Open command prompt
  8.     Start-->run-->type "cmd"  without space
  9. In that command Prompt or DOS screen. Type   net   user  administrator   *        press enter
  10. It will ask for password.Press Enter 2 times and it will say command completed successfully
  11. Now you have sucessfully cracked users Password,without knowing existing password

This is not a hacking,windows had given u feature,thats why u could do it.
