In the process of using Windows XP operating system, we may lose the administrator password for some reason, but how to recover? Here we introduce five kinds of cool trick can effectively recover the password:
up until 1: As you know, Windows XP password stored in the system where the Win NT \\ System 32 \\ CONFIG file under the SAM, SAM file is Account password database file. When we log in to the system, the system will automatically check with SAM in CONFIG. If you find that the password and username are all in accordance with the encrypted data in the SAM file, you will log in successfully; if it is wrong, you will not be able to log in. In this case, our first method is created: delete the SAM file to recover the password.
if you do not control any account originally contained in the system, and there are two operating systems, you can use the operating system to access another NTFS boot the computer, or it is not installed two systems, but you can use other Tools to access NTFS. Then delete the SAM file in the C:\\Win NT\\System32\\Config directory and restart. This is, the administrator Administrator account has no password. Specific performance
security account manager is Systemoot \\ System 32 \\ Config \\ SAM file. The SAM file is the user account database of Windows NT/2000/XP. All users and login information and passwords are saved in this file.
up until 2: Use Office NT PASSWord & REGISTRY EDITOR using the software can make Linux boot disk, the boot disk can access the NTFS file system, so you can well support the Windows 2000 /XP.. Using one of the floppy disks, NTPASSWD, which runs under Linux, solves the problem and can read the registry and rewrite the account. The method of use is very simple, just follow the prompts after startup to do it step by step. Here, it is recommended that you use the quick mode, which will list the user for you to choose to modify that user password. By default, the ADMIN group user is selected, and it is very convenient to automatically find the user who has replaced the name of the ADMINISTRATOR. Download address:

up until 3: Use the Windows KEY 5.0. The software is included in PASSWARE KIT 5.0, used to restore the system administrator's password, after running to generate 3 files: TXTSETUP.OEM, WINKEY.SYS and WINKEY.INF, 3 files a total of 50KB. Put these 3 files on any floppy disk, then use the XP installation CD to start the computer. Press F6 during startup to let the system use third-party drivers. At this point, it is the best time for us to cut in, put the floppy disk will automatically jump to the Windows KEY interface. He will forcibly change the password of ADMINISTRATOR to 12345, so why not make a big deal? Hey! When you reboot, you will be asked to change your password again.

up until 4: Use this tool NTFSDOS can write NTFS partitions from DOS. Use this software to make a DOS boot disk, then rename the screen saver Logon.Scr to C:\\Win NT\\System 32, then copy Command.com to C:\\Win NT\\System 32 (CMD can be used under WIN2000) .EXE) and rename the file to Logon.Scr. After 15 minutes of starting the machine, the screen saver that appears should now become the command line mode, and it has the ADMINISTRATOR permission, so you can change the password or add a new administrator account. Don't forget to change the name of the screen saver back after the change. Download address: http://www.mydown.com

up until 5: Here's a comparison of different methods. 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 back up the boot area MBR in advance. There are many ways to back up the MBR, using tool software 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 NT\\System 32\\Config\\ into the C:\\Win NT\\System32\\Config\\ directory (set up the original XP installation here), and then restore it with KV3000. Grieving the main boot area MBR, now you can log in to XP as an Administrator.
