Windows XP has a much higher security performance than the previous Windows 9X, and we can protect our secrets by setting up a password for individual users, but what if we forget the login password one day? Is there no other way besides formatting the HDD reload system? Let's look for the secret to recovering Windows XP logins.
1. Create a bootable floppy disk to repair the user's password
Microsoft in Windows XP provides us with the ability to create a bootable floppy disk to repair the user's password, and when we forget the password, we can start the computer via this floppy disk, so we should make a password boot disk in case. Click on the "User account" option in the "Start" Control Panel, select your account in the pop-up dialogue window and go to the control screen of your account, then click on the "Block a forgotten password" option in the top left of the window and go to the "Forgot Password Wizard" dialog box. Click "Next", when the wizard prompts to insert a blank formatted disk into the floppy drive, and then click on the "Next" button, the wizard prompts to enter the current account password, after the loser after a few seconds to create a complete password startup disk. When we forget our password one day, just click on the arrow to the right of our account, then click "Reset disk with Password" in the pop-up bar, then insert the previous good password boot disk into the floppy drive and follow the prompts to reset the password and log in to Windows XP. This method is appropriate for Windows XP in a variety of partitioned formats.
2. Remove the Windows XP login password from the dual system
If there are other operating systems in our machine other than Windows XP, you can start with another operating system, and then delete the "SAM" file in the "C:windowssystem 32Comfig" directory (assuming that Windows XP is installed on the C drive), That is, the account password database file. Then restart Windows XP, when the administrator "Administratoc" account has no password. Extrapolate, if there is only one Windows XP system, you can also remove the hard drive and switch the SAM file to other machines.
This method is intended for Windows XP that is installed with FAT32 partitions and, if installed with NTFS partitions, to ensure that other systems can access NTFS partitions.
3. Restore the Windows XP login password using the Ntfsdos tool
First, download a tool called "NTFS dos" from "http://www.vgsecurity.org/index/html?ntfs/html" and use this tool to create a bootable disk that can operate NTFS partitions from DOS. After booting dos, switch to the system directory, such as "C:windowssystem 32", rename "Logon.scr" to "Logon.scr.bak", then copy a "Command.com" and rename the file to "LOGON.SCR". Then restart the machine, when you start the screen saver, you will find that the screen is displayed as command-line mode, and there is ADMINISTRATOC permission, through this can modify the password or add a new administrator account. After you enter Windows XP, change the name of the "Logon.scr.bak" screen saver back. This method applies to Windows XP that is installed on an NTFS partition.
4. Rebuild the Windows XP login password using other tools
Many Windows XP login tools can be found online, such as using the Linux boot disks boot disk to access the NTFS file system, and the ability to read the registry, rewrite accounts and passwords, and use the NT Acess tool to bypass system SYSKEY protection and reset windows nt/2000, Windows xp password, as well as Passware kit, O&obluecon 2000 and other tools, specific operation you can refer to the description of each software.
