How to quickly restore the XP system administrator password three tips

If you install two operating systems, you can use another operating system that can access NTFS to start the computer. If you do not have two operating systems installed, you can use other tools to access NTFS, then delete the SAM file in the C:Windowssystem32config directory and restart the operating system. At this time, the administrator Administrator account has no password. Of course, it is also a good idea to remove the hard drive and switch to another machine to delete the SAM file.
Tip 1: Delete the SAM file to recover the password
Everyone knows that the Windows XP password is stored in the SAM file under the WindowsSystem32Config system, the SAM file is the account password database file. When we log in to the system, the system will automatically collate with the SAM in Config. When the password and username are found to match the encrypted data in the SAM file, you can log in successfully; if it is wrong, you cannot log in. In this case, we can recover the password by deleting the SAM file.
The specific performance of the Security Account Manager is the %SystemRoot%system32configsam file. The SAM file is the user account database of Windows NT/2000/XP, and all the user's login name and password and other related information will be saved in this file.
Tips 2: Use the tool software to recover passwords
Use Off1ine NT Password&Registry Editor. Use this tool software to make a Linux boot disk. This boot disk can access the NTFS file system, so it can support Windows 2000/XP very well. Using one of the floppy disks, Ntpasswd, which runs on Linux, solves the problem and can read the registry and rewrite the account password. The method used is very simple, just follow the prompts after startup to do it step by step. Here, it is recommended that you use the quick mode, which will list the user's password for the user to choose to modify. By default, the user of the Admin group is automatically found to replace the Administrator's name. This is very convenient.
