Vista login password cracking

Vista login password cracking

After I leave the domain today, I forgot my local password and sent it to ITG. I was unwilling to reload the domain. I found an article and read it. The modification was completed. Saves me 2 workdays. Haha, share with you.

Vista logon password cracking is rare. In fact, Microsoft has already "reserved" a backdoor for us on the Vista login interface, so we can easily "Break the window" without using any cracking software ". For the sake of the vistauser interface, the system will start a simple component. We only need to use cmd.exe (command prompt) to replace the components in "easy access" to enter Vista.

Step 2: If you forget your Vista login password, first prepare the Windows Vista installation disc, and then enter the BIOS to set the first boot of the computer to the Optical Drive boot. When a startup prompt is displayed, press any key to start the system from the disc. Click "Next" on the language selection page, and then click "repair computer" on the installation page ", in the displayed "system repair options" window, click "command prompt" (see figure 1 ).

Step 2: Start the "command prompt" and enter the following commands in sequence (the content in the brackets is the command comment, no need to enter, Here suppose Vista is installed on drive C ):
Copy c: \ windows \ system32 \ cmd.exe d :\ (assuming that your Vista is installed on drive c, copy the command prompt to drive d)
Del c: \ windows \ system32 \ osk.exe (delete the Screen Keyboard program in the "easy access" component)
Rename d: \ cmd.exe osk.exe (rename the command prompt as the Screen Keyboard program name)
Copy d: \ osk.exe c: \ windows \ system32 (copy the renamed command prompt to the system directory)

TIPS:
★If you do not have a Vista installation disc at hand, you can use the DOS boot disk to start the system to pure DOS, load NTFSDPS (read/write version), and go to "c: \ windows \ system32" to perform the above operations.

Step 2: restart your computer and exit the CD. On the Vista logon page, click the "easy access" icon in the lower-left corner of the screen, and then select "enable screen keyboard" in the displayed window ", click OK. The command prompt is started (see figure 2 ).

TIPS:
★If the "easy access" icon does not appear, enter any password as prompted. When the system prompts a wrong password, click "switch user" to activate "easy access" in the window that opens ".

Step 2: The "command prompt" run as the administrator is started here. It is actually logged on using the built-in SYSTEM account. Of course, it has the highest SYSTEM permission, now we can use it to access Vista. Next, let's take a look at some practical applications after the system goes around.

Example 1: create a user to Extract files
After you forget your logon password and cannot access Vista, many people are most concerned about how to extract private files from the system disk. Now you can go to the "command prompt" to create a user. Enter "net user CFAN 123456/add" at the "command prompt" to create a user with the username "CFAN" and logon password "123456, then you can use this user to access Vista to extract any files, but remember to delete this new user next time.
TIPS:
You can also enter "net user" to display the current user, and then use "net user CFAN 123456/add" to force the user CFAN (CFAN is an existing user but forgot the password) the password is changed to 123456.

Instance 2: reset the User Password
In the Windows XP era, if you forget your password, you can clear the Windows XP Logon password through EBCD pro. You don't have to worry about Vista. Enter "cmdmmc.exe" in the "cmdname prompt" to start the console, click "File> Add/delete Management Unit", select "local user and group" in the list of available management units, and click "add ". Return to the console window, expand "console section root> local user and group> User", select the account with the forgotten password in the right window, right-click and select "set password ", follow the prompts to change the password. After that, you can return to the logon window and use the new password to log on to Vista (see figure 3 ).

Note:
Changing the account password will cause the EFS encrypted file to fail to be opened. before changing the password, make sure that the encrypted private key has been exported.
