Opening a Dump File Using CDB
Command Prompt
In a Command Prompt window, you can open a user-mode dump file when you launch CDB. Enter the following command.
cdb -y SymbolPath -i ImagePath -z DumpFileName
The -v option (verbose mode) is also useful. For more information about the command-line syntax, see CDB Command-Line Options

You can also open a dump file after the debugger is running by entering the .opendump (Open Dump File) command, followed by g (Go). This allows you to debug multiple dump files at the same time.
