Study Notes: retrieve the computer boot password

Forget the Windows Screen saver password solution: Press F8 after the boot, select safe mode to start, enter Windows, right-click the blank area on the desktop, select "properties"/"Screen Protection" from the shortcut menu to cancel "password protection.

When we use window7, what should we do if we accidentally forget the Windows 7 boot password when the computer sets the user password? The security level of Windows 7 is higher than that of XP. The solution to this problem is different from that of Windows XP.
The simplest way is to press Ctrl + Alt + Delete to open the account window, enter the user name and password, and press Enter.
If the administrator account also has a password, you can:
Press f8.
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?

In addition to the above situations, there are two common cases of forgetting the win7 system password:
1. Forget the password, but you have logged on to the system.
This solution is simple. First, enter "mmc. e xe, or press Win + R to open the Run window and enter "mmc. e xe, and click OK 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 here.

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

1. Find a PE disk and start the computer.
2. Enter PE and go to c: \ windows \ system32.
(1) Change Magnify. E Xe and cmd. E Xe to "administrators ".
(2) Change Magnify. E Xe and cmd. E Xe permissions to full control
(3) Rename Magnify. E Xe to Magnify. E xe1 and cmd. E Xe to Magnify. E Xe.
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 have forgotten 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 click "osk. E Xe "is cut to other locations and" cmd. E Xe is renamed as "osk. E Xe ", and then restart from the hard disk. You can also try to use the Win7 optimization master software to go to The Win7 logon window, click the "easy access" icon in the lower-left corner of the screen, select "enable 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. This is a serious backdoor!
