How to clear the system administrator administrator password

Sometimes we always want to completely delete the administrator password of the windows system, because it is very troublesome to always enter a long string of administrator usernames and passwords before booting. Because computer
always loads a lot of programs before booting, so the wait time for adding the username and password is even longer. The following teaches you how to cancel the administrator password;

clear the administrator password. First delete the SAM file under CONFIG. Then copy the SAM file under the REPAIR directory to CONFIG. The password can be entered. The first thing we need to understand is what is the repair folder? He is located under C:\\WINDOWS When we initially installed the system, we stored a login. Put the corresponding file under C:\\WINDOWS\\REPAIR under C:\\WINDOWS\\CONFIG. We can create a file that can be used to start Windows< Br> XP login configuration file. However, this login configuration file records the basic state of the system at the beginning. For all changes generated in the future, it is impossible to store. Because At the time of system installation, 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 was successful. However, we need to copy software, system, security. , default and sam five files. Not just a SAM file (the author only copied one to enter the system, I think it can only be said to be lucky. Or the hardware information of his computer has not changed much before. This stores your hardware information and some software information. If your hardware or software has a lot of changes, I think. The possibility of not being able to log in is very large.

Because it is the state when the system is installed. This time. Maybe your sound card driver is not installed yet. The graphics card also 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, the settings in the advanced system properties. 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 how much software you installed during system installation) Fortunately, most programs can Normal operation. A small part of the software needs to be reinstalled. Especially some programs loaded in service mode, such as Kaspersky, etc. So it can be solved with the method described in my other post. It should be much better. .

Let's talk about the steps of this operation. (This can be found in Microsoft's knowledge base.) If you have dual systems and another system can enter normally, it will be very simple. You need to copy the five files of software, system, security, default and sam under c:\\windows\ epair to c:\\windows\\system32\\config. Overwrite the original file. Restart it. http://www.bcua .cn

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 be implemented with tools that can identify NTFS partitions. For example, NTFS FOR DOS Then do the following

delete c:\\win Dows\\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\\sam c:\\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 under c:\\windows\\system32\\config. Security, default and sam five files to do a backup. (Add a note: If you have dual system.

These files are copied, cut back to the work of a type of work where you can decide. You can also directly overwrite the file under c:\\windows\ epair. In this case. When you forget the password, you can use the above method. Recovery. And because it is a recent backup. That is to say. When you restore, the software and settings installed on your computer will be the same as when you backed up. This will minimize the loss. Of course. Everything is There is 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 commonly used administrator account login. And the default status of the administrator account The following is not displayed on the login screen. http://www.bcua.cn

After logging in with the administrator account, open CMD. Enter the command in it: net user Your original administrator username " ; new password " then enter. You can change your original user's password to a new password. You can also force the password change in the computer-managed user.

When you log in A folder named administrator.computer_name is automatically created in the c:\\documents and settings folder. There is also a folder named administrator in this folder. The .computer_name behind the previous folder is for The administrator file is different. We only need to restart. Log in with the administrator account after you change the password. Then delete the administrator file. Rename the administrator.computer_name to administrator.

The last step. Give you The administrator sets a strong password. OK
