Administrator password clearing method

        There is another way to clear the administrator password online. Delete the SAM file under CONFIG. Then copy the SAM file under the REPAIR directory to CONFIG. The password can be entered.

I want to point out that this is the author's A coincidence. The first thing we need to understand is what is the repair folder. It is located under C:\\WINDOWS. A login that was stored when we first installed the system. Corresponding to C:\\WINDOWS\\REPAIR When the file is placed under C:\\WINDOWS\\CONFIG, we can create a login configuration file that can be used to start Windows XP. However, this login configuration file records the basic state of the system at the beginning. For all changes that will occur in the future. It is impossible to store it. Because when the system is installed, the password of the default administrator account is empty. So we can log in with a blank password. This is indeed possible. After my experiment succeeded. But. Need to copy the five files of software, system, security, default and sam. Not just a SAM file (the author only copied one to enter the system, I think it can only be said to be fortunate Yun. Or his computer hardware information has not changed much.) This store your hardware information and some software information. If your hardware or software has a lot of changes. I think. Can not log in The possibility is very large. Disadvantages: This method has been given by Microsoft officials. Everyone can't remember the password. You can use this to try. Of course. The disadvantage of using this method is obvious. Because it is the initial installation system Status. This time. Maybe your sound card driver is not installed yet. The graphics card needs to be reconfigured. It may be necessary to install some drivers. Most of the optimizations you have configured for the system will disappear. For example, system properties. Settings in the advanced. Virtual memory settings. Service startup settings.. etc. The Add and Remove programs in the Control Panel will lose most of the program display. (Depending on the software you installed during system installation. How much? Fortunately, most of the programs can run normally. A small part of the software needs to be reinstalled. Especially some programs loaded in service mode, such as Kaspersky, etc. So I can use my other The method described in the post to solve the problem. It should be much better.

Let me talk about the steps of this operation. (This can be found in Microsoft's knowledge base) You have dual system And if another system can enter normally, it will be very simple. Just copy the five files of software, system, security, default and sam under c:\\windows\ epair to c:\\windows\\system32\\config Next. Overwrite the original file. Restart it.

If there is no dual system, if the C drive is FAT32, it can be directly operated under DOS. If it is NTFS, it can also identify NTFS partition. Tools to implement. For example, NTFS FOR DOS. Then do the following

delete c:\\windows\\system32\\config\\system delete c:\\windows\\system32\\config\\software delete c:\\windows\\system32 \\config\\sam delete c:\\windows\\system32\\config\\security delete c:\\windows\\system32\\config\\default

copy c:\\windows\ epair\\system c:\\windows\\system32\\config\\ System copy c:\\windows\ epair\\software c:\\windows\\system32\\config\\software copy c:\\windows\ epair\\sa Mc:\\windows\\system32\\config\\sam copy c:\\windows\ epair\\security c:\\windows\\system32\\config\\security copy c:\\windows\ epair\\default c:\\windows\\system32\\config\\default

Here is a suggestion for everyone. For those who often forget the administrator password. You can do this. Clear the password of the administrator first. Then put the software, system, security, default and c:\\windows\\system32\\config. Sam five files to do a backup. (Add a note: If you have dual system. Please enter another system to backup the system's celebration files. If not. Can be backed up under DOS. Because running in WINDOWS The system will always use these files. The system will not allow you to copy these files, cut the work of a type of work where you can decide. You can also directly cover the c:\\windows\ epair File. In this case. When you forget your password, you can use the above method to recover. And because it is a recent backup. That is to say, when you restore, the software and settings installed on your computer will be backed up. When it looks like this. Loss to a minimum. Of course. Everything has a good side and a bad side. People can also use the above means to enter your system. And it is estimated that you will not know. Because after all, you are not a common administrator. The account is logged in. And the administrator account is not displayed in the login interface by default.

After logging in with the administrator account. Open CMD. Enter the command in it: net user Your original administrator username "New Password" and then press Enter. You can change your original user's password to a new password. You can also force a password change in a computer-managed user.

When you log in at c:\\ A folder named administrator.computer_name is automatically created in the documents and settings folder. There is also a folder named administrator in this folder. The .computer_name behind the previous folder is to distinguish it from the administrator file. Come. We only need to reboot. Log in with the administrator account after you change your password. Then delete the administrator file. Will administ Rename rator.computer_name to administrator.

Last step. Set a strong password for your administrator and disable it.
