1. Remove password using command

Restart WinXP, in the instant after the splash screen, press the F8 key and select "Safe Mode with command line" to run. After the startup process is complete, the system lists the Administrator user Administrator and the normal user ("such as ABC") menu of selections, selects the Admin user Administrator, enters the command line mode and then type the command: "NET user ABC 1234/add", Note! The word "ABC" in the command you typed is the user name you used to use, and the word "1234" is the user's password. The purpose of the command is to forcibly change the login password of the "ABC" user to "1234". If you want to add a user (for example, a username of 321 and a password of 4321), type

NET user 321 4321/add ", add the user to the System Admin Group Administrator user and have super privileges after adding the available" net localgroup Administrator 321/add "command.

Of course, if you have only one WinXP system, you can remove the SAM file by removing the hard drive and switching to another machine.

This method applies to WinXP that are installed with FAT32 partitions, and if installed with an NTFS partition, ensure that the NTFS partitions are accessible to other systems.
