HOWTO: Clear event log


Event Viewer is a tool that displays detailed information as event logs about significant events on your PC.
Event logs are special files that record significant events on your PC, such as when a user signs in to the PC or when a app encounters an error. Whenever these types of events occur, Windows records the event in an event log that you can read by using Event Viewer.
