1. Forgot the power-on password set in COMS: Just discharge the BIOS chip. I won't repeat the specific methods introduced online.
I know the XP login password, but I don't want to use it. If you want to delete it, please open the control panel, select the user account, select the account whose password you want to delete, select Delete My Password, and then follow the prompts.
There are more than two accounts in 3.XP system, one is the administrator account and the other is your own account. Now, you know the administrator password, but you have lost it. You want to reset it: turn on the computer to enter safe mode, and select Administrator login when logging in. Other operations are similar to those in "2".
4. Forgot the XP system administrator password, but know the current user password, and the current user has administrator rights. The operation is similar to "3".
5. I forgot all the login passwords of XP system (maybe I didn't forget them at all, but I don't know at all, I just want to enter the system to see what's inside, (* _ *)), but I can't log in to the system, but I don't want to reinstall the system to recover.
It's a bit complicated, but there are ways:
You can use a software called "DreamPackPL".
(it can be downloaded from/utility/encrpt/dreampackpl20040610.zip).
If you can't download it, you can contact me at QQ: 45507338 1.
How to use:
First, the different operating ideas of DreamPackPL
As shown in figure 1, you can see that there are three options provided here, and the meaning of each option is as follows:
1. Installation: If you have system administrator rights, you can select this option, and the administrator password will be automatically cleared after restarting the system. Obviously, we seldom need to use this option, because there are many options for clearing passwords.
2. Create CD: If you don't have system administrator rights, after selecting this option, the Windows 2000/XP installation CD will be used to create the boot CD. We can use this CD to start the system, and any computer with Windows 2000/XP installed can recover the administrator password in the future.
3. Decompression: After decompression, we will get a file named Sfcfiles.dll, which saves the trouble of burning a CD. We can directly use the Windows 98/Me startup disk to boot the system into DOS mode and replace the file \ Windows \ Windows \ System32 \ sfcfiles.dll.
Second, the password to clear the actual combat
From the above analysis, it can be seen that the most practical option for users who forget their account password is "Create CD". Since they can't access the system, please create a boot CD on another computer with Windows 2000/XP installed. Below, the author briefly introduces the relevant operation steps:
Step 1: Create ISO file
As shown in Figure 2, selecting "Create CD" will guide the user to create an ISO format CD image file, which requires Windows 2000/XP installation CD, and then click the "Mack ISO CD image" button, and the "Save ISO image" dialog box as shown in Figure 3 will pop up, set the path to save the ISO file, and click the "Save" button. Then wait a while to get this ISO file, which contains folders such as BOOTDISK, DISCOVER, i386, SETUPTXT, SUPPORT, VALUEADD and iWebOffice.ocs.asp. The file size is 394.2MB.
Step 2: Burn the bootable CD.
To start the system by burning this ISO file into a CD, you can choose Nero 6 or Alcool 120% and other burning software, but no matter which burning software you choose, please note that you must add a bootable function to it when burning.
Step 3: Replace the file
Start the system with the CD that has just been successfully burned. The Windows 2000/XP installation interface will appear. Please press the "r" key to enter the recovery console. Then, you can see all the Windows operating systems installed in the machine, and select the operating system you need to enter. When you need to enter the password of the system administrator, enter directly to skip this step and enter the command line mode. Type the following command to replace the system link file named sfcfiles.dll:
Ren: \ Windows \ System32 \ sfcfiles.dll sfcfiles.lld (the purpose of backing up this file with a different name is to uninstall DreamPackPL in the future, and it should be \WinNT\System32\ if it is a Windows 2000 system).
Copy H: \ i386 \ pinball.ex _ c: \ Windows \ System32 \ sfcfiles.dll (here H: refers to the drive letter of the optical drive, please enter it according to the actual situation).
In fact, the purpose of the above related operations is to replace the file Sfcfiles.dll, so if your Windows 2000/XP system partition does not use NTFS format, then select "Decompress" in figure 1 to release the sfcfiles.dll file, then boot the system with the WIndows 98/Me startup disk, and then manually replace the file.
Step 4: Reset the password
After completing the above steps, type the "Exit" command to exit the recovery console and restart the system in the normal way. After the welcome screen, a window as shown in Figure 5 will appear. Select "Windows Account Panel" in "Accounts" to enter the user account window, and then we can reset the password, but this will change the original password.
Step 5: Remove the modification marks.
After replacing the Sfcfiles.dll file, the program interface of DreamPackPL will appear every time the system starts or logs off. It is safe to cancel the "DreamPack" option in the "WinNT Unlimited" window before ending the operation.
Of course, in addition to clearing the password, DreamPackPL has many functions, such as full access to the local system, access to EFS-encrypted files or folders in the local system (Windows 2000 system only), or login to the system with a nonexistent account. You may wish to study it carefully when you have time.
When you need to delete DreamPackPL, just restart the system, select "login password check", cancel the "DreamPack" option, and restart the system again. Or boot the system with a burned CD, execute the "DreamPackPL" program in "Bart PE", and select the Windows installation directory to delete DreamPackPL.
Third, use PE version.
If you think the above operation is too troublesome, you can also start from:
/forum/attachment.php？ attachment id = 73/DreamPackPL _ Bart _ PE _ plug . zip
Download the PE version, unZIP the downloaded zip file, then execute the DreamPark.exe file, select the path where Windows 2000/XP is located, as shown in Figure 4, and then click the "Install" button to complete the installation process.
Restart the system, and you will see the window as shown in Figure 5, so I won't say much about the next operation here.
Off-topic: Some friends may think that there are many ways to clear the Windows 2000/XP login password. Why do you have to use DreamPackPL? In fact, what attracts us is not only the generous "free" of DreamPackPL, but its skill of stepping through the snow without trace.
