Final answer:
The setting that forces users to change their password is the maximum password age, which sets the time period after which a password must be updated.
Step-by-step explanation:
The setting that forces users to change their password is known as the maximum password age. This security setting determines the number of days that can pass before a user is required to change their password. When the maximum password age is reached, the system will prompt the user to create a new password the next time they log in. Other settings like minimum password age, password history, and account lockout serve different security purposes but do not directly require users to change their passwords at regular intervals.
