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 (such as a username of 321 and a password of 4321), you should type "NET user 321 4321/add" to promote the user to the System Management Group after adding the "net localgroup Administrator 321/add" command Administrator user, with super privileges. Then restart WinXP, select Normal mode to run, you can use the changed password "1234" to log on to the ABC user. This method applies only to WinXP that are installed with FAT32 partitions and that the user account is not a Chinese character name.
