  • An example is the Dr. Watson tool, which is used in several Windows operating systems from Microsoft and stores the collected data in a log file and a binary file, the so-called crash dump, on the hard disk.
  • Some Windows operating systems also implement error reporting, which collects information from the computer's RAM after a crash and sends it to Microsoft upon confirmation by the user. If the crash is due to a known cause, the user will be given the link to a web page where further information about the problem is available.
