If your Windows PC encounters an error, it will display a Blue Screen of Death or BSOD error which usually comes up for a fraction of second and creates some logs or Dumps Files as what other user prefers to call it and then boots your PC suddenly. This process usually takes place quickly that most users find it hard to get the error code and won’t probably be able to check what really went wrong with their PCs. This is where the dump files come in. They are stored internally in your computer and can only be accessed by an administrator. They are classified into 4 main types and in Windows 10 they are either:

1. Complete Memory Dump
2. Kernel Memory Dump
3. Small Memory Dump (256 KB)
4. Active Memory Dumps

Dump Files are useful as they could help you in resolving the problem and so you need to configure your Windows 10 PC to create them but first, you need to make a system restore point. This is essential as you are about to modify some system files as well as critical Windows 10 settings. There are two ways you can create Dump files – first is by modifying the settings in the Startup and Recovery and lastly is via the WMIC command line. Refer to the instructions prepared below to be guided on how you can create Dump files after any BSOD error using these options.

Option 1 – via Startup and Recovery

• Type in “control panel” in the Cortana Search box and then click on Control Panel from the search results to open it.
• After opening Control Panel, you need to make sure that you view the contents by their Category then click on the header link which is labeled “System and Security” or you could also right-click on the This PC icon and then click on Properties.
• Next, select the Advanced system settings from the left panel. Once you do, a new and small window will pop up.
• Under the newly opened window, look for the section called Startup and Recovery and then click on the Settings button.
• And from the System Failure section, you can choose any option from the drop-down for Write debugging information such as:
  • None – this means that there is no dump file created by Windows
  • Small Memory Dump – this means that Windows will create a Minidump file on BSOD
  • Complete Memory Dump – this means that Windows will create a Complete Memory Dump file on BSOD
  • Automatic Memory Dump – this means that Windows will create an Automatic Memory Dump file on BSOD
  • Active Memory Dump – this means that Windows will create an Active Memory Dump file on BSOD

Note: The complete dump needs a page file that is allowed to be the size of the physical memory installed in your PC with a dedicated 1 MB of space for just the page header.

• Now once you have selected the most suitable option for you, just click on OK/Apply and then exit.
• Restart your PC to successfully apply the changes made.

Option 2 – via the WMIC command line

• The first thing you need to do to create Dump files via the WMIC command line is to tap the Win + X keys combination or simply right-click on the Start button and then select the Command Prompt (Admin) option. You could also type in “cmd” in the Cortana search box and then right-click on Command Prompt from the results and select Run as administrator.
• After that, type in any of the commands given below depending on your preferences so that your Windows 10 PC will be configured to create Dump Files:
  • No dump file: wmic RECOVEROS set DebugInfoType = 0
  • Small Memory Dump: wmic RECOVEROS set DebugInfoType = 3
  • Kernel Memory Dump: wmic RECOVEROS set DebugInfoType = 2
  • Complete Memory Dump: wmic RECOVEROS set DebugInfoType = 1
  • Automatic Memory Dump: wmic RECOVEROS set DebugInfoType = 7
  • Active Memory Dump: wmic RECOVEROS set DebugInfoType = 1

Note: A complete dump has to have a Page file which is allowed to be the size of the physical memory installed on your PC accompanied by a 1 MB space for just the page header.

• Now type in “exit” in the Command Prompt to exit it.
• Restart your PC to apply the changes made successfully.
