Computer users sometimes set a password and forget it, and are helpless in the face of the interface of the operating system that requires a password to log in. In this case, it is not the default administrator account of the system, but the user-defined account (such as ABC), then restart the computer, when starting 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 and press enter the empty enter to log in to the operating system and enter the desktop we are familiar with. After entering, go to the control panel User Account ABC Account and change the password.

The first trick doesn't work? You can also restart your computer by pressing the F8 key as soon as the splash screen appears, and waiting until the safe mode screen appears. Use the up and down keys on the keyboard to select "Safe Mode with Command Line" to enter execution.

After the system load and run is completed, the selection menu of the superuser "administrator" and the local user "abc" will appear, and the mouse clicks the administrator account "administrator" to enter the command line mode. Type the command: "net user abc 123456 add" (force the password of the "abc" user to be changed to "123456").

If you want to add a new user (for example, the username 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 user and make it have super privileges. Restart the computer, select Normal mode, and you can log in to the "ABC" user with the changed password "123456".

If you can enter the system or PE microsystem, you can use the password viewer [Hero Password Viewer].Is rar troublesome? If you have an installation CD in your hand, or a USB flash drive PE microsystem, there are generally gadgets that crack the login password of the operating system.

After entering the PE microsystem, click on the icon, click on the account that needs to be entered (for example: adminstrator) At this time, the button to change the password is available, enter the new password respectively, enter the password again to verify, and click OK. Go back to the main dialog and click Save Changes.

In the security mode without the network, try to see if you can get in, and you can change the password if you can get in.

Hello dear! If you have forgotten your computer's password, you can try the following methods:1

Sign in with an administrator account: If your computer has a bad relationship with multiple administrator accounts, you can use that account to sign in and reset the password for the restricted account. 2.

Use a reset disk: If you've ever created a reset disk, you can reset your password using the celery disk. 3.

Use Windows Safe Mode: You can log in to your computer in Windows Safe Mode and reset your password. 4.

Use third-party tools: There are some third-party tools that can help you reset your Windows password, but using these tools requires certain computer knowledge and skills, and improper operation may lead to data loss or system crash, so please consider carefully. If you still can't solve the problem after trying the above methods, it is recommended to contact a computer repair professional or computer manufacturer's customer service for help.

Here's how:

1. Click "Start Run", enter "rundll32, usersrundll", and press enter.

2. The "User Account" window pops up, unselect the "To use this machine, the user must enter the user name and password" option, click OK, and enter the account and password you want the computer to log in automatically every time in the pop-up dialog box.

I don't know if you set the boot password or the password you set in the BIOS.

If it's a boot password, you can find a ghost system disk, and there is one item that can clear the password.

If it is a password set in the BIOS, it is not easy to clear. It has to be shorted on the motherboard and discharged.

You borrow a boot disk, and many of them have password removal tools.

Is it the administrator password after logging in? Or the boot password of the BIOS.

Three possibilities:

1.Case.

2.If your keyboard does not have a numeric keypad, then it is possible that the default num key is on when you boot up, causing you to enter letters but out numbers, or enter numbers and letters, at this time, just press the numlock key.

3.You do misremember.

The premise depends on whether your boot password refers to the boot password used to log in to the Windows interface or the password set in the BIOS.

1. If it is a Windows password, you can try to restart, press F8 to enter the safe mode, and see if the password of the administrator is empty.

Yes, if so, you can enter the system to change the password of the account you are using now or delete the reconstruction. If you are using the administrator account.

Your administrator account is in the system, and then you can change the administrator's password.

2. If your password is a BIOS password, then you can only remove the motherboard battery, and you can almost clean up the password after 24 hours of discharge.

Hope it helps.

You can unravel it by taking the PE of the system into it.

Are you mixing up the case of your password?

If you want a laptop, you can plug in an external keyboard and try it.
