This way is usually used by developers. Windows traditionally creates a dump file in the system memory that displays applications that were running before the crash occurred. The information you find here could help you troubleshoot the blue screen.
However, to analyze the dump file, you need to use the Windows Driver kit or other similar software. The dump file is usually located in C:\Windows\Minidump.
