How to enter the computer without knowing the password Windows XP 100

Windows XP's powerful and friendly system interface has won the favor of more and more users, but its audit of user security is very strict, if you forget the password (password) you set, don't think that you can choose to "cancel" like Windows98 can also enter the system This is very clear to you who install Windows XP. Of course, this is also after a painful experience, which is only valued by us.

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.

If you're worried about losing your login password, you might want to give this a try.

After pressing Ctrl+Alt+Del twice, the classic login screen appears, the username is administator, and the password is blank. This is only suitable for a small number of computers, and it is generally broken using a PE boot disk.

If you are not using an administrator account. You can boot up to the place where you want to enter the password, press Ctrl+Alt+Del, then type Administrator and press Enter to go in.

If you are using an administrator account. Then you can find a ghost xp installation disc, change the password and boot up. This disc has a password cracking feature.

Another trick is: take off the computer's battery, and the system will return to default. All passwords are cleared. There's a small battery on the motherboard, you look for it!

With a special tool, you can bypass the boot code and turn on the computer without being detected.

Method (1).

Restart the computer, when you boot to the system login interface, hold down the Ctrl+Alt key at the same time, and then click the del key twice, a new login interface will appear, enter the "administrator" password at the user name is empty, press enter to log in, after logging in, open the control panel and select User Account Change Account Click on the original "Account Name" Change my password Enter the new password, enter the new password again, and then click the "Change Password" button.

If you forgot your computer administrator password, use the second method or section.

Three or four methods.

Method (2) 1: Restart the computer, press the F8 button after booting up until the advanced options screen appears, then release your hand and select "Safe Mode of Command Prompt" to enter.

2. At the end of the running process, the system lists the selection menu of the system superuser "administrator" and the local user "**", and clicks "administrator" to enter the command line mode.

3. Type the command: "net user **123456 add" to force the password of "**user" to "123456". If you want to add a new user here (e.g

If the user name is abcdef and the password is 123456), type "net user abcdef 123456 add", and then you can run the "net localgroup administrators abcdef add" command to promote the user to the administrators group and give the user super permissions.

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