File | Open Crash Dump
Click Open Crash Dump on the File menu to open a user-mode or kernel-mode crash dump file and to analyze it.
This command is equivalent to pressing CTRL+D. You can use this command only when WinDbg is in dormant mode.
When you click Open Crash Dump, the Open Crash Dump dialog box appears. Enter the full path of the crash dump file in the File name box, or use the Look in list to find and select the proper path and file name. (Dump files typically end with the .dmp or .mdmp extension.)
After you choose the proper file, click Open.
