Hacking into Windows XP Login Password

This time I wrote about how to overcome the problem of forgotten passwords windows, especially windows xp. This can be used for any computer using Windows XP OS, let's try:

1. When it appears the screen to select the account and the password, press Ctrl-Alt-Del twice. Then the screen will appear containing the name and password box
2. Clear writing on the box and type an administrator name
3. Password does not need to be filled
4. Then press OK. Then straight into windows as administrator.

Once inside, we can change the administrator password. The trick is as follows:

1. Log user account through control panel or by clicking on the top left picture account start menu.

2. Once inside, we can see which user account to computer administrator. For example, the computer account is Faisal. Then to change the password see the next steps are:

# Click START then RUN and when cmd. Then it will go into DOS

# Type in net user and hit enter. It will show the names of the Windows XP user account. Consider one by one the names of the existing user account. Usually the name of the user account when we look at the menu the same user account with which we see through a net user, but sometimes different. Therefore, see one by one equated with that when we look at the menu user account. For example:
On the menu user account, the account that there are:
Faisal
Jafar
Ash
Guest

But an account that looks at the net user:
Jafar
Guest
Ash
Acer
SUPPORT_xxx
IUSR_WINDOWSXP
IWAM_WINDOWSXP
VVSR_WINDOWS_xxx
So in conclusion, the computer administrator Faisal other name is Acer. Attention that SUPPORT, IUSR, IWAM, etc. VVSR not account name.

# After knowing that the administrator account is the Acer then the next step is to type in net user administrator account name space star space. For example:
Acer net user *

# Then the note "type a password for the user:".

If you want a computer administrator password be erased:
Press enter just do not have to be filled, then the note again "Retype the password to confirm:", press enter also do not have to be filled. THEN you have deleted the computer administrator password.

If you want to change the administrator computer passoword:
Fill in the password you want in the "type a password for the user:" and the same password in "Retype the password to confirm:". Notice that the word type the password that we will not look as though we're not typing anything, so you do not need to stay confused just type, guaranteed success.

Good luck !!!
