DumpStack text file is the log that is connected with dump handling in Windows. Based on the particular file and settings of Windows, this log can include information about dump initialization, bug check, or diagnostic data collection process. Sometimes you can open DumpStack.log via Notepad and view its content. Yet, the information provided in this log can be too technical and it might not tell you what caused your computer to fail. Moreover, in order to analyze the situation in detail, you can use memory dump files of Windows for debugging tools. It is better not to change the content of the file as editing will not fix your system issue.
