What is the event ID for reboot?

Excuse me, could you please clarify what you mean by "event ID for reboot"? Are you referring to a specific software, operating system, or hardware component that generates an event log entry when a reboot occurs? If so, it would be helpful to know the context in which you're asking this question, as the event ID can vary depending on the system and the software being used. Additionally, not all systems or software necessarily generate a dedicated event ID for a reboot. Could you provide more details or specify the system you're referring to?
