Method 1: As you know, Windows XP passwords are stored in the SAM file under winnt \ system32 \ config in the system, and the Sam file is the account password database file. When we log on to the system, the system will automatically proofread with Sam in config. If you find that the password and user name are all consistent with the encrypted data in the SAM file, you will log on smoothly; if an error occurs, you cannot log on. In this case, the first method is generated: Delete the Sam file to restore the password. Note: XP does not seem to be able to delete the Sam file to restore the password. It only applies to 2000, so proceed with caution.
If you do not need to worry about any account in the system and have two operating systems, you can use another operating system that accesses NTFS to start the computer, or even if you have not installed two systems, however, you can use other tools to access NTFS. Then, delete the Sam file in the C: \ winnt \ system32 \ config directory and restart. This is because the Administrator account has no password.
The security account manager displays the % SystemRoot % \ system32 \ config \ SAM file. The Sam file is a user account database of Windows NT/2000/XP. All user information, such as logon name and password, will be stored in this file.
Method 2: Use office nt password & Registry Editor. This software can be used to create a Linux boot disk, which can access the NTFS file system, so it can well support Windows 2000/XP. You can use ntpasswd, a tool running in Linux on this floppy disk, to solve the problem and read the registry and rewrite the account. The usage is simple. You only need to follow the prompts after the startup to do it step by step. We recommend that you use the quick mode to list users for you to change the user password. By default, users in the admin group are selected, and users whose Administrator name is replaced are automatically found, which is very convenient.

After running the software package, three files are generated: txtsetup. OEM, winkey. sys, and winkey. INF. The three files are 50 kb in total. Place the three files on any floppy disk, start the computer using the XP installation CD, and press F6 to enable the system to adopt a third-party driver. At this point, it is the best time for us to switch in. If we put this disk, it will automatically jump to the Windows key interface. He will forcibly change the administrator password to 12345, so what will happen? Too many! After you restart, you will be asked to change your password again.

Use the software to create a DOS boot disk, and then go to c: \ winnt \ system32 to set the Screen Saver logon. change the name of SCR and copy the command. com to c: \ winnt \ SYSTEM32 (CMD can be used in Win2000. and rename the file to logon. SCR. In this way, 15 minutes after the machine is started, the screen protection that should have appeared is now changed to the command line mode and has the Administrator permission. Then, you can change the password or add a new Administrator account. Do not forget to change the name of the screen saver. Http://anheng.com.cn/news/23/554.html Method 5: The following describes a different method. You can install an XP system on another partition. The format of the hard disk partition must be the same as that of the original one, and be sure not to install it in the same partition as the original XP! Before you start, you must back up the MBR in the boot zone. There are many methods to back up the MBR. You can use tool software, such as anti-virus software kv3000. After installation, log in with the Administrator. Now you have absolute write permissions on the original xp. You can test the original Sam and use 10phtcrack to get the original password. You can also overwrite all the files in winnt \ system32 \ config \ of the newly installed XP to C: \ winnt \ system32 \ config \ directory (set up the original XP and install it here), and then use kv3000 to restore the previously furious Master Boot MBR, now you can log on to XP as administrator. |
