Crash Detection management must be enforced.
The "Turn off Crash Detection" policy setting allows you to manage the crash detection feature of add-on management in Internet Explorer. A crash report could contain sensitive information from the computer's memory. If you enable this policy setting, a crash in Internet Explorer will be similar to one on a computer running Windows XP Professional Service Pack 1 and earlier, where Windows Error Reporting will be invoked. If you disable this policy setting, the crash detection feature in add-on management will be functional.
