If you have installed a Windows XP operating system and accidentally forgot the system logon user's "***" password, you can run the net command to solve the problem:
The "Net user" command is provided in Windows XP. This command can be used to add or modify user account information. The syntax format is as follows:
Net user [username [Password | *] [Options] [/domain]
Net user [username {password | *}/Add [Options] [/domain]
Net user [username [/delete] [/domain]
The following describes how to restore the "***" password of a local user and how to forget the logon password:
1. restart the computer. Immediately press F8 and select "safe mode with command line" when the startup screen appears ".
2. At the end of the running process, the system lists the system Super User "Administrator" and the local user "*****" selection menus. Click "Administrator ", enter the command line mode.
3. type the command "Net user ***** 123456/Add" and change the "***" user's password to "123456 ". To add a new user here (for example, the user name is abcdef and the password is 123456), type "Net user abcdef 123456/Add ", after adding the account, run the "net localgroup administrators abcdef/Add" command to promote the user to the system management group "Administrators" and grant it super permissions.
4. restart the computer and select "run in normal mode". Then, you can use the changed password "123456" to log on to the "*****" user.
