XP system login requires username and password, but I don t know, what should I do?

Forgot Windows XP login password.

1.Log in with a super administrator password (some people say it's an old routine, yes, although it's old-fashioned but very useful), if you don't set a super administrator password before installing the machine, if you buy a brand machine, then the manufacturer will not set the super administrator password when installing the genuine operating system, and the super administrator password at this time is empty. Enter the Windows initialization login interface and hold down the Ctrl+Alt key, and then press and hold the DEL key twice, then the classic login screen will appear, at this time, type "administrator" in the user name, the password is empty to enter, and then modify the password you need.

Then you can log in as an administrator and change the password in the Home - Control Panel - Administrative Tools - Computer Management - Local Users and Groups.

2.Using the .net command (assuming the username of the user who forgot the password is xucheng), we know that the "net user" command is provided in Windows XP, which can add and modify user account information, and its syntax format is:

net user [username [password | options]] /domain]

net user [username /add [options] [/domain]

net user [username [/delete] [/domain]]

1Restart the computer, press the F8 key continuously after booting, and select "Safe Mode with Command Line".

2. At the end of the running process, the system lists the selection menus of the system superuser "administrator" and the local user "xucheng", and the password of "administrator" is blank to enter the command line mode.

3. Type the command: "net user xucheng 56789 add" to force the password of the "xucheng" user to be changed to "56789". If you want to add a new user here (e.g

If the user name is jimi and the password is 123456), type "net user jimi 123456 add", and then you can use the "net localgroup administrators jimi add" command to promote the user to the administrators group and give them super privileges.

4. Restart the computer, select Normal mode to run, and you can log in to the "xucheng" user with the changed password "56789".

Spend three dollars to buy an XP system disk in Tomato Garden, enter the BIOS, set the computer to a CD-ROM drive to boot, insert the CD and restart the computer, then enter the system tools, find the function of clearing the password, and follow the steps!

Try logging in with the initial administrator account, the username and password are the same, if it doesn't work, reinstall the system.

1) When the computer is turned on, go directly to the BIOS, look for it, and one of the items is to clear the password.

2) As soon as the motherboard battery is disassembled, the password is gone.

No passwords. You click to confirm! Okay, it's mine.
