First, use the net command
The "Net User" command is provided in Windows XP, which can be added to modify user account information, whose syntax format is:
Net user [username [password | *] [options]] [/ domain]
Net user [username {password | *} / add [options] [/ domain]
Net user [username [/ delete] [/ domain]]
The specific meaning of each parameter has been detailed in Windows XP Help, and now takes the step of resolving the login password by recovering the local user "ZHANGBQ" password.
1. Restart the computer, immediately press the F8 key immediately after the startup screen appears, select "Security Mode with Command Line".
2. At the end of the running process, the system lists the selection menu of the system super user "Administrator" and local users "ZHANGBQ". The mouse click "Administrator" to enter the command line mode.
3, type command: "Net user zhangbq 123456 / add", enforce the password of the "zhangbq" user to "123456". If you want to add a new user here (such as the username ABCDEF, the password is 123456), type "Net User Abcdef 123456 / Add", and then use the "NET localgroup administrators abcdef / add" command to increase the user as the system. Manage the user of the "administrators" and make it superior.
4. Restart the computer, select the normal mode to run, you can log in to "ZHANGBQ" users with the changed password "123456".
Second, use "administrator"
We know that during the installation of Windows XP, you should first log in with "Administrator", and then create a new account so that you will use this new account to log in when you enter Windows XP, and only create it in the login interface of Windows XP. This user account does not appear "Administrator", but actually the "administrator" account is still present, and the password is empty.
When we understand this, if you forget the login password, press and hold the Ctrl Alt button on the login interface, then press the DEL button twice, you can display the classic login screen, type in the user name "Administrator", password is empty, then modify the password of "zhangbp".
The latter is relatively easy
