Reboot
This Action is designed for rebooting the computer.Force Applications to Close
During computer shutdown, some running applications can possibly ask a user something on their closure. For example, Microsoft Word having unsaved documents would ask a user to save the changed documents before shutting down.
If the setting is turned off, then if there are running programs that pop up prompts requiring user input, the computer will not be turned off. Therefore, if there are unsaved documents in running applications, the computer will not be turned off.
If the setting is turned on, the operating system will forcedly close all applications even if they require user actions (e.g. save a file). Such applications will be closed anyway after timeout expiration, and all unsaved data will be lost.
