Creating crash dumps on Vista and Windows 7
On Windows 7 and Vista, Windows Error Reporting (WER) has replaced Dr Watson for creating crash dumps.
WER will create a mini-dump file of the process, when the application crashes which has a *.mdmp extension. It is written to the Drive:\Users\UserName\AppData\Local\Temp directory.
You can also access this file by going to Control Panel | System and Maintenance | Problem Reports and Solutions | View Problem History. Highlight the crash, in the list of problems, rigth click and choose "View Problem Details". If a dump was created for the crash, the details will include a link entitled "View a temporary copy of these files". This opens an Explorer window on the directory containing the mini-dump and other supporting diagnostic files. Your can drag and drop these files to another location, to send over to Supportline for example.
