After you log on as an administrator to a computer that is not a member of a domain, when you double-click User Accounts in Control Panel to change the password for the built-in Administrator account, the Administrator account may not appear in the list of user accounts. Consequently, you cannot change its password.
This behavior can occur because the Administrator account logon option appears only in Safe mode if more than one account is created on the system. The Administrator account is available in Normal mode only if there are no other accounts on the system.
To work around this behavior, reset the password in the Local Users and Groups snap-in in Microsoft Management Console (MMC) as follows:
Click Start, and then click Run.
In the Open box, type mmc, and then click OK to start MMC.
Start the Local Users and Groups snap-in.
Under Console Root, expand Local Users and Groups, and then click Users.
In the right pane, right-click Administrator, and then click Set Password.
Click Proceed in the message box that appears.
Type and confirm the new password in the appropriate boxes, and then click OK.
Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
