You can select either some of the events in the Event Log (Audit Trail) with your mouse by left-clicking and dragging, or you can select all events by pressing ‘Ctrl’ + ‘A’. Once the desired events you are looking to export are highlighted, press ‘Ctrl’ + ‘C’ to copy those events, and paste those events into whatever program you would like to store them in, such as Notepad, Microsoft Excel, Microsoft Word, or any other application that can import text.
