[Knowing yt] What should I do if I forget my password?

If a computer is used by many people or needs to ensure computer security, it usually sets the boot password. But what should I do if I forget the boot password?

On the welcome page, press CTRL + ALT + Delete to exit the account window. Enter the username: Administrator and press Enter. If the account also has a password, then:

Press F8 at startup

Select "security mode with command line"

Select "Administrator" and jump out of the "command prompt" window.

Add users: Net user ASD/Add

Administrator: Net localgroup administrators ASD/Add

Restart and select ASD to enter

Control Panel ---- user account ---- user who forgets the password -- delete password?

1. Forget the password, but you have logged on to the system. Click confirm to enter the console. Open "file"-"Add/delete Management Unit" in sequence, find "local users and groups" in the available management unit on the left, and click "add"-"finish" in sequence ", click OK ". Expand the local users and groups in the root node of the console, select "user", right-click the user name on the right, and click "set password". You do not need to enter the original password when downloading the XP system.

2. You have forgotten your password and cannot log on to the system.

① Find a PE disk to start the computer

② Enter PE and go to C:/Windows/system32

(1) Change magnify.exe and cmd.exe to "Administrators ".

(2) Change magnify.exe and cmd.exe permissions to full control

(3rd) Rename magniy.exe to magniy.exe 1 rename magniy.exe .exeto magniy.exe

③ Change Password

(1) Restart to Windows 7

(2) Enable magnifiers

(3) The rest is very simple. Enter the "Net user" command to view the user name, and then enter the "Net user username and new password" command. (Activate the Administrator account to use net user administrator/active: Yes) Close the Command Prompt window and enter the new password you just set in the logon Password box to see if the system has been successfully entered! Finally, don't forget to change all the previously moved and renamed files back. This is a serious backdoor!

④ You forgot your password and cannot log on to the system. This situation is troublesome to handle. I have tried the security mode, fixed the Windows 7 system disk, and logged on to winpe, but I cannot modify the system file. It seems that the method of Vista is not available in the past. My method is similar to the method for modifying files by logging on to winpe. Here we need a Ubuntu installation CD. I use the 8.10 desktop version. Select the disc to start, go to the Ubuntu installation interface, select the language, and then enter the first item "Try Ubuntu without changing ......". Next, wait for the file to be loaded. It will take a little longer. after entering the desktop, open the X:/Windows/system32 folder in Windows 7, and copy the corresponding osk.exefolder to another location, rename cmd.exe "to cmdosk.exe", and restart the hard disk. In the Windows 7 logon window, click the "easy access" icon in the lower-left corner of the screen, select "Start Screen Keyboard" in the pop-up window, and click "OK". The command prompt is started. The rest is very simple. Enter the command "Net user" to view the user name, and then enter the command "Net user username and new password. Close the Command Prompt window and enter the new password you just set in the logon Password box to check whether the system has been successfully entered! Finally, don't forget to change all the previously moved and renamed files back.

All right, the problem is solved, and you will not be afraid to forget the boot password again next time. However, the computer system reminds everyone not to forget the password to avoid troubles.
