About Windows Events

When you are using Windows, the operating system keeps a record of important and useful information about what is happening on the computer. This information is stored in a series of logs known collectively as the Windows Event Log.

There are five types of events that are logged:

  • Information: Lets you know that an application, service, or driver completed an operation.
  • Warning: Informs you of a situation that is probably significant, but not yet a serious problem. For example, low disk space will trigger a warning event.
  • Error: Indicates a serious problem that can cause loss of functionality or loss of data.
  • Success Audit: Records a successful event that is audited for security purposes. For example, when a user successfully logs on to the system, a Success Audit event is recorded.
  • Failure Audit: Records an unsuccessful event that is audited for security purposes. For example, when a user unsuccessfully tries to log on to the system, a Failure Audit event is recorded.

The Event Viewer allows you to view this information by category.
