If you install the Windows XP operating system, inadvertently forget the system login User "* * *" password, you can net command to solve the problem:
The "NET User" command is available in Windows XP to add and modify user account information in the form of:
NET user [UserName [Password | *] [options]] [/domain]
NET user [UserName {Password | *}/add [options] [/domain]
NET user [UserName [/delete] [/domain]]
If this is a domain controller, then enter
NET User Administrator Your-new-password/domain
We now take the example of restoring the local user "* * *" password to illustrate the steps to resolve the forgotten login password:
1, restart the computer, in the Start screen immediately after pressing the F8 key, select "Safe Mode with command line."
2, at the end of the operation, the system lists the system Superuser "Administrator" and the local user "* * *" selection menu, mouse click "Administrator", into the command line mode.
3, type the command: "NET user * * * * * 123456/add", forcing the "* * *" user's password changed to "123456". If you want to add a new user here (for example, the username is abcdef and the password is 123456), type "NET user abcdef 123456/add", which can be added "net localgroup Administrators Abcdef/add" command to promote users to the System Management Group "Administrators" and to have super privileges.
4, restart the computer, select Normal mode to run, you can use the changed password "123456" Login "* * * * * users."
Advantages: simple, safe.
Disadvantage: Can not find other administrator ID password, can only modify, if the use of EFS encryption, encryption damage, data loss.
