How to enable Local Administrator & Create New User account.

Local Users and Groups is a Microsoft Management Console (MMC) snap-in. MMC is a shell program that lets you run most of Windows' system administration applications. An MMC snap-in typically has two panes.

Disable an account—Double-click the user to open the user's property sheet. In the General tab, activate the Account Is Disabled check box.

Add a new user—Make sure that no user is selected and then select Action, New User. In the New User dialog box, type the User Name, Password, and Confirm Password. (I discuss the password-related check boxes in this dialog box later in this chapter; see "User Account Password Options.") Click Create.

Add a user to a group—Double-click the user to open the user's property sheet. In the Member Of tab, click Add and use the Enter the Object Names to Select box to enter the group name. If you're not sure of the name, click Advanced to open the Select Groups dialog box, click Find Now to list all the groups, select the group, and then click OK. Click OK to close the property sheet.
