Tip 1: As we all know, WindowsXP password stored in the system where the Winnt \ System32 \ Config under the SAM file, SAM file that the account password database file. When we log on the system when the system will automatically and Config automatic proofreading in the SAM, such as passwords and user names found in the full SAM file with the encrypted data in line, you will be successful login; if the error can not log on. Being the case, our first method produced: Delete the SAM file to recover your password.
If you do not control the system cards have been included in any account, and there are two operating systems, you can use another operating system can access the NTFS boot the computer, or is not installed although the two systems, but you can use other tools to access NTFS. And then delete the C: \ WINNT \ system32 \ config directory of the SAM file, restart. At this time, the administrator account is no Administrator password. Of course, remove the hard drive change to delete the SAM file onto other machines are also considered a good idea.
Tip: WindowsNT/2000/XP in the safety management of user accounts using the Security Account Manager (Security AccountManager, SAM) mechanisms, security account manager of the account management is carried out through a secure identity, secure identification at account creation At the same time when created, once the account is deleted, the security identity also be deleted. Security identity is unique, even if the same user name each time the creation of security of identity are completely different. Therefore, once an account is deleted, its security identity no longer exists, that is, using the same user account name of the reconstruction will also be given a different security identity, does not retain the original is not permissions.
Security Account Manager is a concrete manifestation of% SystemRoot% \ system32 \ config \ sam file. SAM file is WindowsNT/2000/XP user account database, all the user's login name and password and other related information will be saved in this department file.
Tip 2: Use Off1ine NT Password & Registry Editor. The software can be made with the Linux boot disk, the boot disk can access the NTFS file system, so you can very well support Windows2000/XP. Using the floppy disk in a run in Linux tools Ntpasswd can solve the problem. And can read the registry and rewrite the account password. The method used is very simple, just based on their step by step post-prompt to do on it. In this, I suggest you use the fast mode, so that the user will be listed for you to choose which changes the user's password. Is selected by default Admin group of users, automatically find the name of the Administrator replace the user, is very convenient.
Tip 3: Use the Windows Key 5.0. The software included in the PasswareKit5.0 that are used to restore the system administrator's password, running generates three files: txtsetup.oem.winkey.sys and winkey.inf, 3 files total of only 50KB, dapper. Any of these three files on a floppy disk, and then start the computer using the XP installation CD to start the process by pressing F6 key to allow the system to install third-party drivers. At this point, what we get into the best time to release them to the floppy disk will automatically jump to WindowsKey interface. It will force the Administrator password changed to "12345", and this will not a big worry? Ha ha! When you restart later, you will be asked to change your password again.
Tip 4: Use NTFS DOS This can be written under the NTFS partition from DOS tools. Use the software to make a DOS boot disk, and then to C; \ Winnt \ System32, under the screen saver logon.scr renamed, then copied command.com to the C: \ Winnt \ system32 Next (2000 can use cmd.exe), and rename the file logon.scr. This starts the machine, after waiting for 5 minutes, this should appear the screen saver is now the command-line mode, but also with Administrator privileges, it can be modified by adding a new administrator password or account of. Exhausted Do not forget to change the screen saver's name changed back ah. Download: http:/www.cgsecurity.org/index.html?
Tip 5: Here's a more unusual approach. You can install in other partition and then an XP, hard disk partition format should be the same as the original, and must not draw your attention to the original installation of XP on the same partition! Before you begin, be sure to back up pre-boot MBR (Master Boot Record). There are many ways the backup MBR, it can do programming, or using tools, such as antivirus software, etc. KV3000. Zhuang Wan Administrator log on later, and now you have the original XP written permission of the absolute. You can copy down the original SAM, with lOphtcrack get the original password. Can also be the new installation of XP, Winnt \ System32 \ Config \ all the files under the cover C \ Winnt \ System32 \ Config directory (assuming the original XP installed on here), and then restore the previous backup KV3000 master boot record MBR Now you can use Administrator logged the previous XP.
Tip: MBR commonly known as the "master boot record," its role is to read the disk partition table (Partition Table) which set the active partition (Active Partition), located on the hard disk cylinder 0, head 0, Sector 1 position, that is vulgar 0 track of your location. It is produced by the partition fdisk command. MBR, including the hard disk partition table boot process and these two points. MBR end of the logo 55AA, use anti-virus software KV3000 the F6 function to view, and its default screen shall be MBR. If the MBR can not find the active partition, it will display on the screen, like Missing operating System such as error messages, so if you can not normally open the WindowsXP. And you see on the screen an error message like this, because many of them are out here, the
