My computer set a password on the boot system, but I forgot the password

Method 1: 1Start XP at boot when you see it"Windows XP is being started"When prompting the interface, press"f8"key to bring up the system boot selection menu, select"Safe mode with command execution".

2.When the operation is stopped, the administrator and other users will be listed in the selection menu (in this case, xp01 is used as an example for other users), and the adminstrator and enter will be selected to enter the command mode.

3.Type the command: net user xp01 1234 add This is the command to change the password for that user"1234"This is the new password after the change, and if the typed user xp02 does not exist, then the system will automatically add this user.

4.It can also be used"net localgroup administrator xp01/add"command to promote user xp01 to superuser with all privileges.

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

Method 2: There is a simpler one, that is, when the input password dialog box appears, press Ctrl+Alt+Delete 2 times in a row to enter the user name dialog box, at this time, as long as you enter the administrator without the password you can enter, if this is useless, the administrator has set the password, the above method is useless, you can't enter the command prompt mode. Unless you make a boot disk.

1. Restart the machine, use the "F8" key to bring up the system boot selection menu, select the first item, and enter the safe mode.

2. Enter the account from the security mode and create a new user in the Administrator group.

3. With this user account, you don't need to think about the original forgotten password and continue to use the computer.

However, this method is not a way to crack the password, it can only help you if you need to use the computer and cannot access the computer.

Looks like you can't get into the system, right? In this case, only the "Discharge Method" can clear the settings in the BIOS. We can find the CMOS jumper on the motherboard (see motherboard manual), short it for a few seconds, and then turn it back on.

If you can't find the jumper, you can find the coin cell battery on the motherboard and take it down. Use copper wire (as long as it can conduct electricity) to short-circuit it, so that the effect is the same, no need to read the motherboard manual.

The following is the difference and connection between BIOS and CMOS.

The BIOS is an EPROM or EEPROM chip on the motherboard, which contains important information about the system and a setup program for setting system parameters (BIOS Setup program); CMOS is a readable and writable RAM chip on the motherboard, which contains specific parameters about the system configuration, and its content can be read and written through the setup program. The CMOS RAM chip is powered by a backup battery, so even if the system loses power, the information will not be lost. BIOS is both related and different from CMOS :

The system setup program in the BIOS is the means to complete the CMOS parameter setting; CMOS RAM is both the place where the BIOS sets the system parameters and the result of the BIOS set system parameters. Therefore, the full statement should be"The CMOS parameters are set through the BIOS setup program"。Since BIOS and CMOS are both related to the system settings, the BIOS settings and CMOS settings are actually the same thing, but BIOS and CMOS are two completely different concepts, so they must not be confused.

1. Restart the machine, use the "F8" key to bring up the system boot selection menu, select the first item, and enter the safe mode.

2. Enter the account from the security mode and create a new user in the Administrator group.

3. With the user account, you don't need to think about the forgotten password and continue to use the computer.

Press F8 on power and select the safe mode with the command prompt line.

Enter after entering.

net user netfriends 123456 add enter, net localgroup administrators netfriends add enter.

After successfully restarting the system, you will find that there are more users netfriends, and the password for entering the system with the new user is 123456, and you can delete the previous user.

Go to DOS, type net user administrator, then press enter, restart, your password is empty, just go in directly to the place where you want to enter the password, you don't need to enter any password, you don't need to press anything.

Enter the security mode and reset the password.

Is there an option for the BIOS to change the password?

Remove the motherboard.

CMOS batteries.

The computer quickly rotted and forgot the password to solve the Zhenchang solution.

Go to the mobile phone store and get it done quickly.

It can't be a BIOS password, right? If you have a common boot password, and you are not using the "original" system administrator, adminstrator can press the key combination twice on the screen where the password is entered, "Ctrl+Alt+del" to enter the security mode, and enter the adminstrator password in the account by default. If you are using this account with a password, then reinstall the system, reinstalling the system is the easiest at this time.

Well, since there are so many restrictions, no software, no disk, no safe mode, only unplug the battery on the motherboard, and discharge it for half an hour. This way your password will disappear automatically, *** is the BIOS settings restored to factory settings.

Go to the computer repair shop and change the hard drive, or go to the computer company to crack it, don't tell me that I forgot the password of someone else's computer, then I can't do anything!!

The 2nd floor is hilarious! Is the motherboard battery an ornament? Press F8 to enter the safe mode when entering the system, and then open an account.

Dude: You can go up to the place where you bought a computer and buy a disk with a broken password.

Crack the Windows boot password, what should I do if I forgot the Windows boot password.

Method: Use.

PE discs. Boot the system (some ghost system disks with a toolbox also have this function), and on the screen where the options menu appears, press the arrow keys to move to.

Clear the administrator password", and then press the enter key to quickly clear the "administrator account" password;

Take out the system CD and restart it to clear the password, administrator account, and log in to the system.

If the administrator account also has a password, then you can only find a ghost installation disk and put it into the CD-ROM drive, restart the computer and press the del key to enter the CMOS, set the CD-ROM drive to start first, and press "F10" to save and exit the CMOS settings, restart the computer again to enter the ghost installation interface, there is an option to clear the boot password, click on it, and follow the prompts step by step.

The premise is that there is a USB flash drive boot disk.

Question: I don't have this.

Question: I don't have this USB flash drive boot disk.

Then enter cmd mode.

Bypass the password through **,But this project is too large and complicated and in addition to win7,Other systems don't seem to be possible.。

Ask if there's an easy way to do it.

AnswerYes,There is no boot disk,CMD if you don't use it,The easiest thing is to send it for repair but it's not worth it,It's better to make a boot disk,You can also use it repeatedly to reinstall or repair the system if you have something to do in the future,U disk boot disk is a good choice more13

Buy a system disk, and now the system disk has the function of deleting passwords. Just like installing the system, set the optical drive to boot and select Remove Password. It's solved, it's clear.

Use the super administrator to enter the system, that is, press F8 before entering the system after booting, select security mode, enter the system, go to the user account of the control panel, and clear the password of your current administrator.

When you turn on the computer, keep pressing F8 until the safe mode appears, click the safe mode to start, and then enter the control panel and delete the password

Delete the password with the PE system, or the system disc has it! ·· It's very simple
