Event logs grow in size as you work on your computer, but Event Viewer provides tools that help you view just the information you need and store the information you want to save for later. For example, you can apply a filter that allows you to view only events matching specified criteria, such as all events associated with a certain user. You can also search for a specific event using similar criteria. You probably don’t want your active log to include events that happened long ago. With Event Viewer, you can archive, or save, your log periodically and then clear the archived events. Most administrators archive event logs on a regular schedule.
