This how-to guide will tell you tell steps to configure, and allow or prevent Windows 10 to create dump files for BSOD/stop error analysis.

Whenever a crash happens, Windows displays Blue Screen of Death (BSOD) or stop error. To fix BSODs, we need to exactly know the system image at the time of crash. Dump files are those files which will provide us details of this kind. They will tell us what was executing at the time of crash along with what was present in application’s memory. This will help us to locate the BSOD fault so that we can proceed accordingly and troubleshoot it.

A dump (.DMP) file is usually analyzed by a dump analyst or using dedicated tools. All you need to do is to allow Windows 10 to create dump files and if a crash occurs, collect the dump files and post your query to Microsoft Answers/Community or Technet IT Pro forums. The BSOD analysts present there will help you to solve the issue.

There are 5 type of dump files:

1. Small memory dump: It provides minimum set of information about why system crashed.

2. Kernel memory dump: It records kernel mode read/writes on physical memory while crash happened.

3. Automatic memory dump: Same as Kernel memory dump, except Windows sets system paging file for this type of dump.

4. Active memory dump: Provides information about both kernel and user mode.

5. Complete memory dump: It offers all the information about Random Access Memory at the time of crash.

You can read about them in detail in this support article.

By default, Windows 10 creates Automatic memory dump file. You can follow these steps to configure, which type of dump files should Windows 10 create.
