9 solutions to forget Windows XP login password
--------------------------------------------------------------------------------
First propose:
If you are a very easily forgotten, so don't forget to create a startup disk to restore Windows XP account password in the password the first time at the same time, it can let you avoid hard disk trouble.
From the \their own account access control interface as shown in the figure, we can see a \side of the task list, click the \password can open the wizard, the wizard will be prompted to insert a formatted a blank disk, in the process of operation will let you enter the account password, can quickly create a password reset disk.
Later, when we forget when the account password, without the use of \press Ctrl + Alt + Del key combination, \window, click the options in the \password\button, the window appears to change the password. In this window, backup the current user's password, click the \corner, activate the \password reset disk according to the hint.
If the wrong password has been entered in the Windows XP login window will pop-up \failed\window, if you do what is not up to your own password, you can click the \start the password reset wizard, by just creating a password reset disk, you can use this password change the password reset disk and boot the system. Reset your password and log in to Windows XP.
\because anyone can use this a password reset disk to login Windows XP, can enter the user account in the name of the user, the user can operate all the real operation, it must be \reset disk\keep in place, to prevent loss or leakage.
Method 1 - use the \(this method applies to the administrator username and not the administrator)
We know that the installation of Windows XP process, the first is the \default login, then create a new account to enter Windows XP using this new account login, but also in the Windows XP login screen will only appear in the user account creation, not a \
\empty.
When we understand this, if you forget the password, the login screen, hold down the Ctrl+Alt key, and then press the Del button two times, can appear the classic login screen, then type the user name \enter the password is empty, and then modify the password \
Method 2 - delete the SAM file (note that this method applies only to WIN2000)
Windows NT/2000/XP in the security management of the user account using a security account manager (Security Account, Manager, SAM) of the management mechanism, security account manager on account is carried out through safety signs, safety signs in the account creation is also created, once the account is deleted, security identification also deleted. Security identifiers are unique, even if the same user name is completely different from each other when they are created. Therefore, once an account is rebuilt by the user name, the account will also be given different security labels and will not retain the original permissions. The specific feature of the security account manager is the%SystemRoot%system32configsam file. The SAM file is the user account database of Windows NT/2000/XP, and all the user's login names and passwords are stored in this file.
Knowing this, our solution has also been created: deleting the SAM file, starting the system, and it will rebuild a clean, clean SAM with no password inside.
However, such a simple approach is not applicable in XP, and Microsoft may be limited to BUG...... So now in the XP system, even if you delete the SAM, or can not delete the password, but will cause the system to start initialization error, so as to enter the dead loop, but can not enter the system!!
Method 3 - find the password from the SAM file (premise)......
You can use the DOS basic command
Insert boot disk before the system starts,
Entry: C:WINNTSystem3Config copies the SAM file to the floppy disk using the COPY command. Get another machine to read. Here the tool is LC4, run LC4, and open a new task, and then click IMPORT to Import from SAM file \to be cracked, open the SAM file, then LC4 will automatically analyze the file, and displays the file name; click the\Session - Begin Audit \you can start crack password. If the password is not very complicated, it will get results in a very short time.
However, if the password is complex, it will take a long time, and then we need to use the following method.
Method 4 - overwrite with other SAM files (provided you 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 simply replace the SAM file to replace the login name and password. However, the \format of this replacement SAM file is the same as for your system (see FAT32 or NTFS, and you can confirm it yourself). The \of the best system there is no password, security settings did not move (in fact, most of the personal computer are like this, of course, more insurance) way is to put all the files of the XP [Win NTSystem 32Config] [C:Win NTSystem 32Config] to cover the directory in your XP installation (assuming the default partition in C:),
