For your own computer sometimes there are always some private things do not want others to see what should be done? What we often do is to set the password, so as long as they know the password people can not use their own personal computer, the problem of the administrator password you know how much? What should I do if I forget the admin password?
The "NET User" command is available in Windows XP, which allows you to add and modify user account information in the following syntax format:
NET user [UserName [Password | *] [options]] [/domain]
NET user [UserName {Password | *}/add [options] [/domain]
NET user [UserName [/delete] [/domain]]
The specifics of each parameter are described in detail in Windows XP Help, and are not discussed here.
First, now to restore the local user "ZHANGBQ" password for example, to resolve the forgotten login password steps:
① Restart the computer, press F8 key as soon as the splash screen appears
② Select Safe Mode with command line.
At the end of the ③ run, the system lists the Select menu of the system Superuser "Administrator" and the local user "ZHANGBQ".
④ mouse click "Administrator" to enter command line mode.
⑤ type command: "NET user Zhangbq 123456"
You can force the password of the "ZHANGBQ" user to be changed to "123456".
Restart the computer, select Normal mode to run, you can use the changed password "123456" to log in to the "ZHANGBQ" user.
Second, if you want to add a new user (such as: User name is abcdef, password is 123456),
Please type "NET user abcdef 123456/add",
Add users to the System Management Group "Administrators" with the "net localgroup Administrators abcdef/add" command and give them super privileges.
NET Command method applies only to WinXP that are installed with FAT32 partitions and that the user account is not a Chinese character name. This is a test that I've tested, but to add, under Safe Mode with Command prompt, after you add a user and elevate it to superuser privileges, because there are no "start" and "Shut down" and so on in Safe Mode with command line, only a black screen, you must enter "Exit", When you exit the command prompt, press the "Ctrl+alt+del" key combination and then restart after you save the setting by selecting Shutdown---Restart system (or shut down system) in the prompt box, and you can change the password for the other account after you enter the system because it is a superuser. Otherwise, the added ledger does not have super permissions, only users in the user group, and cannot change the password for other accounts.
Third, clear the XP login password
Windows XP password is stored in the system's Winntsystem32config Sam file, the Sam file is the account password database file. Log on to the system, the system will automatically and config in the Sam automatic proofing, such as the discovery of this password and the user name is full with the SAM file in accordance with the encrypted data, you will log on smoothly, if the error can not log in. If you don't need to manage any of the accounts that your system card contains, and you have two operating systems, you can start the computer using another operating system that has access to NTFS, or you can use other tools to access NTFS, although you do not have two systems installed. Then delete the Sam file in the C:winntsystem32config directory and reboot. At this point, the admin administrator account will have no password.
Administrators "Administrator"
When Windows XP is installed, it is first logged in as "Administrator" and then creates a new account to log in with this new account when you enter Windows XP, and only this user account that is created in the Windows XP login interface will not appear. Administrator, but the "administrator" account actually exists, and the password is empty. If you forget the login password, in the login interface, hold down the Ctrl+alt key, and then hold down the DEL key two times, you can appear classic login screen, at this time in the user name type "Administrator", the password for empty entry, and then modify the "ZHANGBQ" password can be.
Through the above explanation, I think we have a solution to the problem of the administrator password forgotten, after that, I am not afraid to forget the password this question, I hope for those who need help.
