Changing How Event Log Overruns are Handled

Written by Barry Dysert (last updated June 1, 2020)

The system's event logs don't grow forever. By default, when they hit their maximum allowable size Windows deletes the oldest log file entries and continue to write new ones. You can change this default behavior if you wish.

For example, let's say that I want to change how the System event log's overruns are handled. I can do so by following these steps:

  1. Display the Event Viewer. (The easiest way to do this is to use the search capabilities of Windows to look for "Event Viewer", without the quote marks.)
  2. In the Navigation pane (left side of the Event Viewer), expand the Windows Logs node and click on System.
  3. In the right pane, click Properties. Windows displays the Log Properties dialog box for the System event log. (See Figure 1.)
  4. Figure 1. Changing how log overruns are handled.

  5. Using the three radio buttons at the bottom of the dialog box, specify what you want to happen when the maximum log file size is reached.
  6. Click OK.

The three options for handling large log files may need a bit of explaining. Windows provides these options:

  • Overwrite Events as Needed. This is the default behavior, i.e., the oldest events are deleted to make room for the new events.
  • Archive the Log when Full. The event log is automatically archived and a new one is created. No events are lost. This is a good choice if you think that there may be some events occur on your system which result in a rapid escalation in the number of events being logged.
  • Do Not Overwrite Events. The event log is cleared, and new ones get written to the empty log file. It is unclear how this choice could ever be desirable, but there you have it.
