Crack Xp login password method

If you are a very easy to forget person during the use of XP, then don't forget to create a boot disk that can restore the password of the account in Windows XP at the same time you set the password for the first time. It can save you. The trouble of formatting the hard disk.

Find the "User Account" item from the "Control Panel" and select your account to enter the control interface as shown in the figure. We can see that there is an item in the task list on the left side. A forgotten password & rdquo;, click to open “ Forgot Password Wizard & rdquo;, the wizard will prompt to insert a formatted blank disk, the operation will let you enter the password used by the account, very soon You can create a password reset disk.

Later, when we have forgotten the account password, after logging in to Windows XP without using the "Welcome Screen" login method, press “Ctrl + Alt + Del” In the “Windows Security” window, click the “Change Password” button in the option and the Change Password window appears. In this window, backup the current user's password, click the “Backup” button in the lower left corner, activate “Forgot Password Wizard”, and follow the prompts to create a password reset disk.

If you enter the wrong password in the Windows XP login window, the "Login Failure" window will pop up. If you really can't remember what your password is, click “Reset&rdquo ; button, start the password reset wizard, through the password reset disk just created, you can use this password to reset the password and start the system. Reset your password and log in to Windows XP.

 The creation of a password reset disk" is dangerous because anyone can use this "password reset disk" to log in to Windows XP, you can use this user The name enters the user account and operates everything that the real user can operate, so you must keep the “password reset disk” in the appropriate place to prevent loss or loss of confidentiality.

Method 1——Using “administrator” (This method applies to administrators whose username is not “administrator”)

We know that during the installation of Windows XP, the first is Log in as default by “administrator”, then ask to create a new account to log in to Windows XP with this new account, and only the created user account will appear in the Windows XP login interface, and will not appear. Administrator”, but in fact the "administrator" account still exists, and the password is empty.

After we understand this, if you forget the login password, on the login screen, hold down the Ctrl+Alt key and then press the Del key twice to display the classic login screen. At the user name, type “administrator”, the password is empty, and then modify the password of “zhangbp”.

Method 2——Delete SAM file (note that this method only works with WIN2000)

Windows NT/2000/XP uses a secure account manager for secure management of user accounts ( The security account manager (SAM) mechanism, the security account manager manages the account through the security identity, the security identity is created at the same time when the account is created, and once the account is deleted, the security identity is also deleted. The security identity is unique, and even with the same username, the security identity obtained each time it is created is completely different. Therefore, once an account is rebuilt by a username, it will be given a different security ID and will not retain the original permissions. The specific performance of the security account manager is the %SystemRoot%system32configsam file. The SAM file is the user account database of Windows NT/2000/XP. All users' login names and passwords are saved in this file.

Knowing this, our solution has also been created: delete the SAM file, start the system, it will rebuild a clean and innocent SAM, which naturally has no password.

However, such a simple method is not applicable in XP, Microsoft may use this as a BUG, ​​made a restriction … … so now under XP system, even if you delete the SAM, you can not delete the password On the contrary, it will cause the system to start initialization error, and thus enter the infinite loop and can not enter the system!!

Method 3—— Find the password from the SAM file (premise …… will use DOS basic commands)< Br>

Before the system starts, insert the boot disk and go to: C:WINNTSystem3Config Use the COPY command to copy the SAM file to the floppy disk. Get another machine to read. The tool needed here is LC4, run LC4, open and create a new task, and then click “IMPORT→Import from SAM file” to open the SAM file to be cracked. At this time, LC4 will automatically analyze this file and display the file. Username in the middle; then click “Session→Begin Audit”, you can start cracking the password. If the password is not very complicated, the result will be obtained in a short time.

However, if the password is more complicated, it will take a long time, then we need to use the following method.

Method 4——Overwrite with other SAM files (provided you can get the SAM file of another computer and its password …… personally think it is the most feasible way)

1—— As mentioned above, the SAM file holds the login name and password, so we just need to replace the SAM file to replace the login name and password. However, the replacement SAM file should be the same as your system (see FAT32 or NTFS, you can confirm it yourself). It is best that the system of "Place of Origin" has no password, the security settings have not been moved (actually a large part of the PC is like this), of course, the more insurance way is to put XP under [Win NTSystem 32Config] All files are overwritten in the [C:Win NTSystem 32Config] directory (assuming your XP is installed in the default partition C:),

2—— if you don't get help from others (I mean “ In case, you can install an XP system on other partitions, the hard disk partition format should be the same as the original, and please be careful not to install the same partition with the original XP! Before you start, be sure to There are many ways to back up the MBR and back up the MBR, using tools such as anti-virus software KV3000. After installing it, log in with Administrator. Now you have absolute write permission to the original XP. You can test the original SAM and get the original password with 10PHTCRACK. You can also overwrite all files under the newly installed XP Win NTSystem 32Config into the C:Win NTSystem 32Config directory (install the original XP installed here), and then use the KV3000 to restore the previously grievous main boot area MBR, now you can Log in to XP as an Administrator.

Method 5——Use Win 2000 installation CD to boot the repair system (premise …… is obvious? You have to have a Win 2000 installation CD)

Using Win 2000 installation CD Start the computer, select Repair Windows 2000 in the Wndows2000 installation selection interface (press R); then select Use Faulty Console Repair (press C), the system will scan the existing Window2000/XP version. There is usually only one operating system, so only one login option is listed (l:C:Windows). Press l from the keyboard, then press Enter. At this time, Window XP does not require the administrator password to be entered. Instead, it logs directly into the Recovery Console mode (if you are using the Windows XP installation CD, it is required. Enter the administrator password. The administrator here refers to the system's built-in Administrators account.) Windows-familiar friends know that the Recovery Console can perform any system-level operations, such as copying, moving, and deleting files. Start, stop services, and even destructive operations such as formatting, repartitioning, and more.
