One minute to crack the Windows system power-on password

Windows system power-on password has been relished since Windows 98, the earliest password protection can be described as a virtual design. Until the later Windows 2000 input method vulnerability, Microsoft realized the seriousness of the problem, and how about the security of the password in the face of a widely used Windows XP system? How to modify or break the system verification without the correct password?

First, the CD crack system password

Search for "crack XP password" on the network will see a lot of information, most of which are said to crack the Windows XP operating system password is not universal Sex can only solve the password problem of the individual version of the operating system; some can't even be realized at all. And using "ERD COMMANDER" can successfully crack the Windows XP/2003 operating system password, just to solve the password problem, the effect is absolutely great! Since the prototype of this tool is system maintenance, we are only using one of the very small components. But still need to prepare a blank disc.

The program default is just an ISO image file. The image file is burned onto the disc using a disc burning software such as "Nero". Then set the boot order of the computer to the CD-ROM drive priority in the BIOS of the computer.

Boot the computer with this CD. At startup we will find that its startup interface is very similar to Windows XP. When the startup is completed, you can enter the setting interface of ERD COMMANDER. If the user has two or more operating systems installed at this time, select the system that needs to crack the password. When the selection is complete, specify the keyboard layout and time zone of the system, and click the "OK" button to complete the setup.

Go to the “ERD COMMANDER” desktop and open the system main menu “Start” → “Administrative Tools” → “Password Change” to enter the password setting wizard dialog box. . Click the "NEXT" button in the dialog box to enter the password setting page. Select the account you want to set a password for, enter the same password in the "New Password" and "Password Confirmation" fields, and finally click the "NEXT" button to successfully change the account password in Windows XP.

Special note: Nowadays, the methods of online circulation are all using SAM files. This method will cause problems that cannot be entered into the system after cracking the password. SAM file is the security account management database. (Security Accounts Management Database), which is the core of the NT architecture operating system (including Windows NT/2000/XP/2003). The security account manager manages the user account through the security identifier SID. Each SID is generated when the system adds an account. Once an account is deleted, its corresponding SID is also deleted. Even if we build another identical account right away, the newly generated SID values ​​are different. The method of deleting the SAM file to crack the password is only valid for the win2000 operating system, but it is not valid for Windows XP/2003.

Second, 1 minute to solve the system password

The following is a better way for everyone: simple, safe, and the success rate is 100%, so that you are not looking for the system password "System" is sighing!

First download a gadget with only 20KB, download address: http://active.zol.com.cn/security/password.rar, because the software must run under DOS (nonsense, if you can Enter Windows to crack the password?), so you need to make a boot disk containing the password.exe file in advance, use it to boot the system and run password.exe. As for the boot disk, there are many ways to boot the system. Just run the password.

select the first mode to enter custom, 1 press Enter.

Select the system partition, because the author operates on the virtual machine, so there is only one partition, you can also determine which is the C drive according to the capacity, select the corresponding serial number and press Enter. .

The software automatically searches for the password file and confirms with Enter.

The user list appears, select the corresponding user (recommended to choose the user name in green status), press Enter to confirm.

The software asks if the password is cleared. Press Y and press Enter to confirm.

The corresponding user password has been cleared, and the carriage return returns to the main interface.

After restarting the system, log in with the user who just cleared the password and find that you can enter the system directly.

Special Note: If you have multiple systems installed, you may search for multiple password files, you need to select the password archive path of the corresponding system.

Third, the use of U disk alternative crack method

In summary of the two methods, coping with the system password is more than enough, but here the editor still has to introduce a novel method, because its entire crack The idea is very novel and can provide us with more room for expansion.

I wonder if you noticed that when the computer is in the login interface and asks for a password, you press the windows key +U, if there is an auxiliary tool management tool, since the auxiliary tool can be run, it means that Run the components inside, such as a magnifying glass. Can we change the magnifying glass program to other programs? What if this program can add users?

First make a U disk that can start the computer. The reason why U disk is selected is because of its versatility and can be applied to crack other computers. The following is the creation of the user's exe file, here you need to do an excessive, because there is no ready-made program can be completed, we first write a batch file, the content is as follows:

@net user zol 123456 /add

@net localgroup administrators hack /add

@exit

The above command means to create a user named zol and then add it to the administrator group. Use BATEXE to convert to exe, download address: http://active.zol.com.cn/security/BATEXE.rar, which needs to be converted to com file, then convert com file to exe. Finally, rename the generated file to magnify.exe and replace the file under system32.

If the password is forgotten, press the windows key +U, run the magnifying glass, create a new administrator, and then press Ctrl+Alt+Del twice to log in with the new account and password. However, the biggest drawback of this method is that it only applies to forgotten passwords. It does not work for computers that are not ready for the pre-production.
