Forgot or don't know how the WINDOWS XP login password, the author's computer is installed by a Windows XP operating system, accidentally forgot the password of the system login user "zhangbq", and does not do the corresponding emergency disk when installed, so Finding the author hoping to solve this problem, after a number of methods, finally I finally found two ways to solve the problem, and now introduce these two methods as follows: First, use net commands We know in Windows XP "NET User" command, this command can be added, modify user account information, its syntax format is: Net user [username [password | *] [options]] [/ domain] net user [username {password | *} / add [ Options] [/ domain] net user [username [/ delete]] The specific meaning of each parameter has been detailed in Windows XP Help, and this author will not explain. Ok, we now take the step of recovering the local user "zhangbq" password as an example, the step of solving the login password: 1, restart the computer, press the F8 key immediately after the startup screen, select "Security mode with command line ". 2. At the end of the running process, the system lists the selection menu of the system super user "Administrator" and local users "ZHANGBQ". The mouse click "Administrator" to enter the command line mode. 3, type command: "Net user zhangbq 123456 / add", enforce the password of the "zhangbq" user to "123456". If you want to add a new user here (such as the username ABCDEF, the password is 123456), type "Net User Abcdef 123456 / Add", and then use the "NET localgroup administrators abcdef / add" command to increase the user as the system. Manage the user of the "administrators" and make it superior. 4. Restart the computer, select the normal mode to run, you can log in to "ZHANGBQ" users with the changed password "123456". Second, using "Administrator" We know that during the installation of Windows XP, first is logged in with "Administrator", and then ask a new account so that you can use this new account to log in when you enter Windows XP, and log in to Windows XP The created user account will only appear, and "Administrator" will not appear, but the "administrator" account is still present, and the password is empty. When we understand this, if you forget the login password, press and hold the Ctrl Alt button on the login interface, then press the DEL button twice, you can display the classic login screen, type in the user name "Administrator", password is empty, then modify the password of "zhangbp". How, users who forget the Windows XP login password still don't hurry to try it.
