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 can't remember what your password is, click the “Reset” button to activate the password. Set up a wizard to reset the password with the password you just created, you can use this password to reset the password and start the system. Reset your password and log in to windows xp. & ldquo; password reset disk & rdquo; the creation of a certain degree of danger, because anyone can use this "password reset disk" to log in windows xp, you can enter the user account in the name of the user, Operate everything that a real user can do, so you must keep the "password reset disk" in the appropriate place to prevent loss or loss of confidentiality. Method 1 & mdash; & mdash; use “administrator” (This method applies to the administrator user name is not "administrator" situation) We know that in the process of installing Windows XP, first login with "administrator", and then will be required to create A new account, use this new account to log in when entering Windows XP, and only the created user account will appear in the windows xp login interface, there will be no “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 this time, type in the username. “administrator”, the password is empty to enter, and then modify the password of “zhangbp” Method 2 & mdash; & mdash; delete SAM file (note that this method is only applicable to WIN2000) Windows NT/2000/XP security management of user accounts using the Security Account Manager (SAM) mechanism, secure account management The management of the account is performed by the security identifier. The security ID is created at the same time when the account is created. Once the account is deleted, the security ID 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, ​​doing restrictions … … So now under XP system, even if you delete the SAM, you can not delete the password, but will make the system boot Initialization error, so enter the infinite loop and can not enter the system!! Method 3 & mdash; & mdash; find the password from the SAM file (premise … … will use the DOS basic command) Before the system starts, insert the boot disk, enter: C: WINNTSystem3Config Use the COPY command to copy the SAM file to a 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 & mdash; & mdash; covered with other SAM files (provided that you can get the SAM file of another computer and its password … … personally think that is the most feasible way) 1 & mdash; & mdash; As mentioned above, SAM file is saved With the login name and password, then 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 "just 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 starting, be sure to backup the boot area MBR in advance, backup MBR There are a lot of methods, using tool software, such as anti-virus software KV3000, etc. After loading, use Administrator to log in, now you have absolute write permission to the original XP, you can test the original SAM, use 10PHTCRACK to get the original password 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 KV. 3000 to restore the former sorrowful main boot area MBR, now you can log in to XP as an Administrator.
