How do you clear messages from a Custom View in Event Viewer to display only today's events?

Editing the Custom View properties to set a date range is the correct approach because this allows you to refine the data displayed in the Event Viewer without losing the custom criteria you have already set. Custom Views are designed to filter and display events based on specific parameters, and adjusting the date range effectively narrows the focus to just today's events.

By selecting a specific date range, you can interactively filter the events to show only those that occurred within that timeframe. This method is efficient and leverages the functionality of the Event Viewer to tailor the data being viewed according to your needs, ensuring that important events are readily visible while minimizing clutter from older entries.

Other methods, such as deleting the Custom View and recreating it, would eliminate any configurations you had previously set, meaning you'd have to start from scratch. Exporting and re-importing events is an unnecessary complication for this task, as it doesn't address the need for a quick and straightforward filtering of the displayed data. Closing and reopening the Event Viewer would not affect the view settings and would leave you with the same unfiltered results as before.
