Local Account Manager is a tool you can use to manage local user and group accouts. With Local Account Manager you can easily add, modify, delete users and groups (manage security accounts), change account properties, assign user rights and privileges on Windows XP Home like within Windows XP Professional administrative tools (Local Users and Groups, User Rights Assignment).
Local Account Manager can be used not only for creating, deleting or renaming users. You can add a user to a group, define privileges for groups or users, permit or deny to perform a security task for any account or temporary disable a user.
It allow you to restrict access to confidential and unwanted information, and also prevents inexperienced users from damaging the system (making system-wide changes, backing up system files and folders, shutting down a computer, etc).
Also you can change a password for any user even if you forget the password and can't recover it. You can define that user must change the password on next logon or deny changing a password by a user in the future.
