To disable Internet Explorer Error Reporting

To disable Internet Explorer Error Reporting so that the default operating system error handler is shown if a crash occurs, set the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Main

IEWatsonEnabled = (DWORD) 0
DWNeverUpload = (DWORD) 1
DWNoExternalURL = (DWORD) 1
DWNoFileCollection = (DWORD) 1
DWNoSecondLevelCollection = (DWORD) 1

A value of 0 disables Internet Explorer Error Reporting, and a value of 1 enables it (removing the key also enables Internet Explorer Error Reporting).

If you do change Internet Explorer Error Reporting to report to an internal server, you should refer to the Office XP Resource Kit and the documentation for the "Corporate Error Reporting Tool" to view and diagnose which crashes should be reported to Microsoft to find a possible fix.

Note Internet Explorer Error Reporting (IEER) does not work in Windows XP or later versions. Windows Error Reporting (WER) is used instead. If WER is disabled and Internet Explorer encounters a fault, no notification is displayed.
