Emergency method for losing Windows XP login password

A friend called to say that his xp could not be logged in. The machine is installed by me and the administrators password I remember, the system FAT32 partition, and did not make the corresponding emergency disk during the installation, I really do not want to face the installation process again, so I conducted an analysis and test of the internal commands of Windows XP Successfully solved the problem with the NET command, and now publish the method and discuss with the peers. The syntax of the NET command in Windows XP is: Net [accounts| Computer| Config| Continue| File| Group| Help| Helpmsg| Localgroup| Name| Pause| Print| Send| Session| Share| Start| Statics| Stop| Time| Use| User| vIEw] The net user command is to add or modify user accounts or display user account information. It is also an important command to be used by this method. The syntax is: net user [UserName [PassWord |  *] [options]] [/domain] net user [UserName {PassWord |  *} /add [options] [/domain]] net user [UserName [/delete] [/domain]] The meaning of each parameter can be found in Windows XP help information. Ok, let's get to the point, to restore the local user "OWNER" password as an example. To solve the login password, forget the method: 1. Restart Windows XP. At the moment after the startup screen appears, press F8 and select "with command line." The safe mode "runs. 2. When the running process is stopped, the system lists the selection menus of the super user administrator and the local user owner. Click the administrator button to enter the command line mode. 3. Type the command: "net user owner 123456 /add", forcibly change the password of the OWNER user to "123456". If you want to add a user here (for example, the username is abcdef and the password is 123456), type "net user abcdef 123456 /add". After adding, you can use the "net localgroup administrators abcdef /add" command to promote the user to the system. Manage group administrators users with super privileges. 4, restart Windows XP, select the normal mode to run, you can log in to the OWNER user with the changed password "123456". This method is only a kind of emergency measure after the login password is forgotten. Of course, there are many other methods and tools, and the author is here to inspire the jade.
