Note: This information applies only to the password for logging in to the Windows XP operating system. If you have forgotten your password for logging in to a computer running the Windows XP operating system, there are a few different options: If you created a password reset disk for windows XP, you can use that disk to reset the password on your acount. For more information on how to create and use password reset disks go to the the Microsoft Knowledge Base.
If you want to know another utility way to reset the password of any user that has a valid local account on your XP system, by modifying the crypted password in the registrys SAM file. You do not need to know the old password to set a new one.
It works very excellent, that is, easy to solved your problem just take you 5 minutes.
It also creates a password recovery CD/DVD,USB Flash Drive for home, business and enterprise.
Today I also want to talk "Administrator Account Not Used for Logon"
The administrator account and password created during setup are used to log on in safe mode only. To create a password for user accounts, double-click manage users in control panel.
Therefore, if you are propted for the user name and password (or if you are prompted only for the password) when you use the net use command(but not because you used an asterisk[*] in the net use command for password prompting) and the /savecred switch, the credentials are saved.
(1) When you type the net use
* \ computer_name share_name /savecred command,
the user is prompted for a user name, and then the user is prompted for a password.
(2) When you type the net use
* \ computer_name share_name /u: domain_name user_name /savecred command,
the user is prompted for a password.
(3) However, when you type one of the following commands, a key is not created:
net use * \ computer_name share_name * /user: domain_name user_name /savecred
net use * \ computer_name share_name * /savecred /user: domain_name user_name
If you type net help use at a command prompt, more information is displayed about the net use command.
Hope these can help you.
