I. ExploitationNetCommand We know that 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: Net user [username [Password | *] [Options] [/domain] Net user [username {password | *}/Add [Options] [/domain] Net user [username [/delete] [/domain] The specific meaning of each parameter has been described in detail in the help of Windows XP, and I will not elaborate much here. Now, we will take the "zhangbq" password of the local user as an example to illustrate how to forget the logon password: 1. restart the computer, press F8 immediately after the startup screen appears, and select "safe mode with command line ". 2. At the end of the running process, the system lists the selection menus of system Super User "Administrator" and local user "zhangbq". Click "Administrator" to enter the command line mode. 3. type the command "Net user zhangbq 123456/Add" and change the password of "zhangbq" to "123456 ". To add a new user (for example, the user name is abcdef and the password is 123456), enter "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" to log on to the "zhangbq" user with the changed password "123456. 　　Ii.
