In windows xp, the administrator account is not logged in. How can this problem be solved?

If an Administrator account is set up during Windows XP installation, the Administrator account without password protection is not displayed in the User Logon list. Although it is behind the scenes, it has the highest system permissions. To facilitate operations and ensure system security, you can set a password for it and then bring it to the stage. The following describes the specific methods.

1. Log On with the "Traditional logon prompt"

When you start the system to the welcome screen, press CTRL + ALT + Delete twice and enter the user name and password of the Administrator account in the logon box that appears. You can also click "Start> Control Panel" and double-click the "User Account" icon. In the displayed "User Account" window, click "Change User Logon or logout method ", remove the check box before "use welcome screen" and click "application options" to directly enter the Administrator account name and password to log on at startup.

2. The Administrator account is displayed on the logon welcome screen.

Click Start> Run, enter regedit, press enter, open the Registry Editor, and expand the branch "HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows NT \ CurrentVersion \ Winlogon \ specialaccounts \ userlist" in sequence, change the value of Administrator on the right to 1 to display the Administrator account on the logon welcome screen.

3. Automatically log on to the administrator account

Click Start> Run, enter control userpasswords2, and press Enter. In the displayed "User Account" window, remove the check box before "to use the local machine, you must enter a password, press "application", enter the Administrator account password (1) in the pop-up "automatic login" window, and press "OK" twice. NOTE: If other accounts have been configured to log on automatically, select the check box before "to use the local machine, the user must enter the password" and press "Apply" Before removing the selected check box. You can also modify the Registry to Enable Automatic Logon. However, the preceding method is not convenient.
If you do not need an administrator account, you can choose "Start> Control Panel> Management Tools> Computer Management". In the "Computer Management" window, expand System Tools → local users and groups → users, and double-click the Administrator account in the right window of user, in the pop-up "properties" window, select the check box before "the account has been disabled" (2), and press "OK" to disable the administrator account.
