Hint for software developers. In Windows Vista SP1 and Windows Server 2008 you can instruct Windows Error reporting to always create a process memory dump by setting this registry value in either

• HKEY_CURRENT_USER\Software\Microsoft\Windows\Windows Error Reporting\LocalDumps
• HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Windows Error Reporting\LocalDumps

This is useful because per default Windows Error Reporting does not create a dump for every error.
