You can configure the actions that Windows takes when a system error (also referred to as a bug check, system crash, fatal system error, or stop error) occurs. You can configure the following actions:

Write an event to the System log.
Alert administrators (if you have set up administrative alerts).
Put system memory in a file that advanced users can use for debugging.
