How to create a minidump file to fix the BSoD error

Almost all Windows users are familiar with the Blue Screen of Death (BSoD) error unfortunately. BSoD occurs when the Windows system encounters problems that can affect safe system operation, such as problems with third-party driver code, hardware, or Microsoft code. To solve the blue screen error, users can use a minidump file.

What is Minidump file?

A minidump file is a file that contains the information about the nature of the system crash. It is created just before the blue screen appears and it has the minimum amount of useful information that can be used to solve the problem. The minidump file usually has a .dmp extension.

note

On Windows 10, the blue screen shows a stop code and a QR code. The user can use this information and search the Web for the specific problem.

The option to create the minidump file is disabled by default, so before we go into more detail on how to use the file, let’s take a closer look at how to enable it.

Set up Windows to create the Minidump file

Even if you don’t experience any BSoD crash errors, you can still set this option — this is a general recommendation, not necessarily related to AdGuard products. Please follow the instructions below to automatically create the minidump file.

  1. Type sysdm.cpl in the Windows search bar and click Open. The System Properties Control Panel Menu window will appear on the screen.

  4. Click OK to apply the settings.

  5. Restart the computer.

You've successfully enabled the minidump file. Now it will be created automatically when the system crashes.

note

By default the minidump file is stored in the %SystemRoot%\Minidump folder. You can change the directory location to whatever you like, but please remember that a lot of programs are set to look for this location by default, so we recommend that you do not change the location.
