How to Enable MiniDumps on Windows 11: Step-by-Step Guide to Fix Crash Errors

Windows 11 sometimes crashes unexpectedly, leaving you wondering what went wrong. One useful way to diagnose these crashes is by enabling MiniDumps. MiniDumps are small files that capture important information when your system crashes.

These files help you or a technician understand the cause of the crash. Enabling MiniDumps is a straightforward process that can make troubleshooting much easier.

In this guide, we will walk you through how to enable MiniDumps step-by-step on Windows 11. Each step is explained in detail to ensure even beginners can follow along.

By the end, you will have the tools you need to collect crash data and better fix system errors.

Quick Note: Prerequisites Before You Begin

  • Administrator Access: You need to be signed in as an administrator to change system settings.
  • Basic Computer Knowledge: Familiarity with Windows Settings and File Explorer will help.
  • Disk Space: MiniDump files are small but ensure you have enough free space on your system drive.
  • Backup: It’s always a good idea to back up important data before modifying system settings.

Step 1: Open System Properties

The first step to enable MiniDumps is to access the System Properties window. This window allows you to change settings related to system performance and error reporting.

  1. Press Windows + R on your keyboard to open the Run dialog box.
  2. Type sysdm.cpl and press Enter. This opens the System Properties window.

This method is quick and direct, avoiding multiple clicks through menus.

Step 2: Navigate to Startup and Recovery Settings

In the System Properties window, you need to find the settings that control how Windows handles system failures.

  1. Click on the Advanced tab at the top.
  2. Under the Startup and Recovery section, click the Settings button.

This section controls what happens when your PC encounters serious errors, including creating MiniDump files.

Step 3: Enable and Configure MiniDump Files

Now you will enable the MiniDump and specify where Windows should save the dump files.

  1. In the Startup and Recovery window, look for the Write debugging information dropdown menu.
  2. Select Small memory dump (256 KB) from the dropdown. This option creates a MiniDump file that captures essential crash details without using much disk space.
  3. Confirm the Small dump directory path is set to %SystemRoot%Minidump. This is the default folder where MiniDumps will be saved.
  4. Make sure the checkbox Overwrite any existing file is checked. This allows Windows to replace old dump files with new ones, keeping the folder uncluttered.
  5. Click OK to save the settings, then click OK again to close the System Properties window.

Setting the correct dump type and folder is important for easy access and for diagnostic tools to read the files later.

Step 4: Verify the MiniDump Folder

After enabling MiniDumps, it’s a good idea to check that the designated folder exists and is ready to receive dump files.

  1. Open File Explorer by pressing Windows + E.
  2. Navigate to C:WindowsMinidump.
  3. If the folder does not exist, right-click inside C:Windows, select New > Folder, and name it Minidump.

Having this folder in place ensures that crash dump files are saved correctly when a crash occurs.

Alternative Method: Using Registry Editor (Advanced Users)

If you prefer or need to enable MiniDumps through the Registry Editor, follow these steps carefully. Editing the registry incorrectly can cause system problems, so back up your registry first.

  1. Press Windows + R, type regedit, and press Enter.
  2. Navigate to the key: HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlCrashControl
  3. Find or create the following DWORD values and set them as below:
    • CrashDumpEnabled – set to 1 (for MiniDump)
    • MinidumpDir – set as a string value to %SystemRoot%Minidump
  4. Close Registry Editor and restart your computer to apply the changes.

This method is useful for system administrators or when GUI options are unavailable.

Frequently Asked Questions (FAQs)

What is a MiniDump file?

A MiniDump file is a small memory dump that records essential information about your system’s state when it crashes. It helps in diagnosing the cause of the crash.

When Nothing Works: Final Steps and Resources

If you’ve enabled MiniDumps but still cannot diagnose or fix your system crashes, consider these options:

  • Use Windows Reliability Monitor: Search for “Reliability Monitor” in the Start menu to view recent system errors and warnings.
