What is the username under which you log in?

As long as you are not the administrator, you can restart the computer, press the F8 key to enter the safe mode, under normal circumstances, the administrator does not have a password, and after entering the WinDOS XP system in the safe mode: My Computer Right-click - Manage - Local Users and Groups - Users, and select the username you want to log in.

For example, guest, right-click - set a password, and you can enter a new password. Hehe!!! In this case, it is advisable to change the guest password without knowing the original password.

Hehe, it's better not to use this method to do bad things, and occasionally you won't be legally responsible.

This is no longer possible in the face of the new system, if it is your own system, reinstall the system and copy it out (if there are any important files in the first system folder). It's okay to delete the previous dos. Nothing important is reloaded and overwritten.

Someone else's. I do not know.

Unable to enter the system because there is no login password; The first method was always to reinstall Windows XP, but this method was cumbersome, time-consuming and labor-intensive, and after many experiments, I finally found a way to crack the Windows XP login password without any other software:

But to crack the login password, there are two necessary prerequisites:

1.The partition on which Windows XP is installed must be based on the FAT32 file system;

2.There are no Chinese characters in the username.

After confirming that these two conditions are met, you can perform the following steps to crack the login password.

1.Start Win XP at boot, when running to the prompt interface of "Booting Windows XP", press the "F8" key to bring up the system boot selection menu, and select "Safe Mode with Command Line";

2.When the operation is stopped, the selection menu of "administrator" and other users will be listed (other users in this example take xpuser01 as an example), select "administrator" and press enter to enter the command line mode;

3.Type the command ""net user xpuser01 1234 add" This is the command to change the password of the user, "1234" in the command is the new password after the change, if the typed user does not exist (xpuser01), then the system will automatically add this user.

4.In addition, you can use the "net 1oca1group administrator xpuser01 add" command to upgrade the xpuser01 user to a superuser and have all the permissions.

5.The last step is to restart your computer and enter the new password you just changed in the login window.

To crack the password, you only need to enter the PE system, you can search for Xiaoyi Electronic Technology in Taobao, or add Wangwang: Qingyuexiang, buy a system USB flash drive, permanently solve the system problem, one-click installation, you can also become a computer master. XP, Win7, Win8, Apple system, free remote maintenance for life with one purchase.

8g Kingston and SanDisk USB flash drive, only less than 30 yuan, the store is newly opened, the lowest price.

First method:

1. Restart the computer, press the F8 key immediately after the boot screen appears, 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 "zhangbq", and clicks "administrator" to enter the command line mode.

3. Type the command: "net."

userzhangbq

add" to force the password of the zhangbq user to be changed to 123456. If you want to add a new user here (e.g., username abcdef, password 123456), type "net."

userabcdef

add", after adding, you can use "net

localgroup

administrators

abcdef

add" command promotes the user to the user of the system administration group administrators and gives it super privileges.

4. Restart the computer, select Normal Mode to run, and you can log in to the "zhangbq" user with the changed password "123456".

Use "administrator".

We know that in installing Windows

During the XP process, you will first log in as "Administrator" by default, and then you will be asked to create a new account in order to access Windows

XP when logging in with this new account, and also on Windows

In the login page of XP, only the created user account will appear, and "administrator" will not appear, but in fact, the "administrator" account still exists, and the password is empty.

When we understand this, if you forget the login password, on the login interface, hold down the CTRL+ALT key, and then press and hold the del key twice, the classic login screen can appear, at this time, type "administrator" in the user name, the password is empty to enter, and then modify the password of "zhangbp".

The second method:

Click Start Run and enter rundll32

usersrundll", press the enter key and then pop up the "User Account" window, see clearly, this is different from the "User Account" panel window opened in the "Control Panel"! Then uncheck the "To use the machine, the user must enter a username and password" option, click OK, and enter the account and password you want the computer to automatically log in to each time in the pop-up dialog box.
