This is the simple Hack tech which may you all know but I want to share this.
You can hack into Windows XP without using any softwares as like "Login recovery"
Just do the following steps:
1.When you log on to Windows XP normally you will see the Login screen like this.
2.In the Login screen press Ctrl+Alt+Del twice.
3.Then the screen will changes as shown below.
5.You will be automatically logged on to the Administrator account where you can access every files of other users and even you can disable others user account also.
NOTE: This tech will not work when the user had already set a password for the Administrator account .
