Source: Windows Central On Windows 10, a crash dump file is usually created automatically when a critical error occurs with the information about the system memory, which you can then use to analyze and determine the reason for the issue. Although these files are created automatically, sometimes, it may also be necessary to make them manually. For instance, when the app is not responding, and you have to send details to technical support for analysis and troubleshooting purposes. Or if you are building an application, and you need to find out why it's using a lot of system resources, such as processor and memory.
