I believe that all of you have experienced a computer is placed in front of you, but it is because the system has been set up the password can not enter the pain it. Enter with a blank password for the default administrator account? Many computers do not have this loophole. Use software such as WinPE to change your password? This can not be changed back to the original password, will let the machine owner found. Here we teach you to use WinPE to enter the XP system with no trace of the password.

Let me first say the principle: we know that XP is using X:\Windows\System32\config (x as the system is the drive letter) under the SAM file Storage System user account information, where the user name and password is stored in this file. When the computer enters the system, it automatically reads the stored encryption string for comparison to confirm the accuracy of the password. From this we can think of, when we use the program in WinPE to modify the password, the SAM file is backed up, the original password is saved in the backup folder. When the password has been modified to enter the system to use the computer, you can re-enter WinPE to restore the file (because the SAM file under XP is protected, not removable), that is, the system to restore the original password, so that the password has been cracked without leaving traces of the mother.

Well, after understanding the principle, let's take a look at the actual procedure.
First, we need an external storage device for a WinPE system, a USB flash drive, a CD-ROM, and set it as the preferred startup item in the BIOS so that it can go directly to the WinPE system when the computer starts.
Then, under PE to enter the X:\Windows\System32\Config directory, find a file called Sam, copy and paste into the same directory, you can get copies of Sam.
Then, in WinPE find the ERD or other password modification tool, click on the ERD target Windows. Then select the Windows directory under the drive letter of the computer Windows system, note that you must select to the directory, you can not just select the drive letter.
After the finished, then from the beginning to find the ERD, click "Modify the login password of the target Windows", according to the program prompts to change the system password, restart the computer, you can use the password you set to enter the operating system.

When we use the computer, but also to change the password back, you can enter WinPE again, still come to the X:\windows\system32\config directory, the SAM file is deleted, and the copy Sam renamed Sam, the backup Sam file restore. In this way, the password is changed back to the original computer owner set the password.

If you want to use this computer frequently, you can also copy the SAM file to a USB stick, and then another computer with Saminside to extract the password hash value, the hash to crack, you can know the password of this computer. ）：

2. Specific methods

You can refer to this website:

I put the main paste as follows: (which is the time of operation (that is, the win PE and some external software engraved into the U disk), to see carefully after the operation, do not put the computer format.

This place is going to be right, it should be, your U-plate.

Picture I posted here, these are not a problem for people who use Windows frequently.

If you want to make a change without knowing it, you can restore it after you've used it, in this way (as the article begins), as follows:

Then, under PE to enter the X:\Windows\System32\Config directory, find a file called Sam, copy and paste into the same directory, you can get copies of Sam.
Then, in WinPE find the ERD or other password modification tool, click on the ERD target Windows. Then select the Windows directory under the drive letter of the computer Windows system, note that you must select to the directory, you can not just select the drive letter.
After the completion, and then from the beginning to find the ERD, click "Modify the login password of the target Windows", according to the program prompts to change the system password, restart the computer, you can use the password you set to enter the operating system

Note: OK, so that you can make the password changes, but in the middle I omitted a lot of details ....
