Note: This article focuses on Windows 10 system crash dump settings created after serious system failures, not app-specific dump files generated by developer tools or Task Manager.
When Windows 10 crashes hard enough to throw a Blue Screen of Death, it usually leaves behind a little souvenir: a memory dump file. That file is basically Windows saying, “I have fallen, and here are my notes.” For everyday users, it may look like useless digital clutter. For troubleshooters, IT admins, and anyone who has ever stared angrily at a random reboot, it can be incredibly useful.
If you want Windows 10 to create a different type of memory dump file, you absolutely can. Maybe you want smaller files to save storage. Maybe you need more detailed crash data to diagnose a stubborn driver issue. Maybe you just discovered a giant MEMORY.DMP file and realized your computer has been writing novels behind your back. Whatever the reason, changing the dump type is straightforward once you know where to look.
In this guide, you’ll learn how to change the type of memory dump file Windows 10 creates, what each option means, when to use each one, and what to watch out for so your system doesn’t quietly refuse to create the dump you expected.
What Is a Memory Dump File in Windows 10?
A memory dump file is a snapshot of system memory created when Windows encounters a fatal error. It helps capture what the operating system, drivers, and sometimes user-mode processes were doing right before the crash. That information can then be reviewed with tools like WinDbg or other crash-analysis utilities.
In plain English: when your PC faceplants, Windows tries to write down what happened before it blacks out.
Depending on your settings, Windows 10 can create different dump file types. Some are tiny and fast to save. Others are huge and full of detail. The right choice depends on whether you care more about saving disk space or collecting enough data to troubleshoot serious stability problems.
Why Change the Memory Dump Type?
There are several good reasons to change your Windows 10 crash dump settings:
1. You want smaller dump files
If you are low on storage, a complete memory dump can be a beast. On a machine with 16 GB or 32 GB of RAM, that file can get very large, very quickly.
2. You need better troubleshooting data
A small dump is convenient, but it may not include enough detail to identify the real cause of a crash. If you are debugging repeated BSOD errors, a kernel or complete dump often gives you a much better shot.
3. You manage multiple systems
IT teams often standardize crash dump settings so every machine produces a consistent kind of diagnostic data. That makes post-crash analysis a whole lot less chaotic.
4. You want more control over storage and overwriting
Windows lets you choose not only the dump type, but also whether to overwrite existing files and where the dump gets stored. That matters if you are trying to preserve crash history or keep a system drive from turning into a clutter museum.
Types of Memory Dump Files in Windows 10
Before you change anything, it helps to know what the choices actually mean.
Small Memory Dump (Minidump)
This is the lightweight option. A minidump stores the smallest amount of information needed to help identify the problem. It is much easier on disk space and is often stored in the %SystemRoot%\Minidump folder.
Best for: casual troubleshooting, systems with limited storage, and users who want a crash history without giant files.
Trade-off: because it contains limited data, it may miss the deeper cause of the crash.
Kernel Memory Dump
This option records only kernel memory, which includes the Windows kernel, drivers, and other kernel-mode components. It is usually much more useful than a minidump while still being smaller than a complete dump.
Best for: most advanced troubleshooting scenarios, especially when you suspect driver or system-level problems.
Trade-off: it still takes more space than a minidump and depends on having enough paging file support.
Complete Memory Dump
This is the full buffet. A complete dump records all physical memory in use when the crash occurs. It offers the most detail, but it can also produce a very large file. On systems with lots of RAM, that can become a serious storage consideration.
Best for: deep debugging, developer-level analysis, and situations where maximum crash data matters more than storage.
Trade-off: it requires a paging file on the boot drive large enough to support the dump, and the file can be enormous.
Automatic Memory Dump
This is often the most practical middle-ground option. It captures the same information as a kernel memory dump, but Windows manages the paging file size more intelligently to improve the odds that the dump can actually be created.
Best for: most users who want useful crash data without manually tuning everything.
Trade-off: it is convenient, but it still relies on Windows managing the paging file properly.
Active Memory Dump
An active memory dump is similar to a complete dump, but it filters out pages that are less likely to matter for troubleshooting. Think of it as a full dump that went on a diet.
Best for: advanced scenarios where you want more detail than a kernel dump but not quite the size of a full complete dump.
Trade-off: it is more specialized, so many everyday users never need to touch it.
How To Change the Type of Memory Dump File Windows 10 Creates
Here is the standard method using the Windows 10 interface.
Step 1: Open System Properties
Press Windows + R, type sysdm.cpl, and press Enter. This opens the System Properties window directly. It is the old-school control panel route, but for this setting, old-school still gets the job done.
Step 2: Go to the Advanced Tab
In the System Properties window, click the Advanced tab.
Step 3: Open Startup and Recovery Settings
Under the Startup and Recovery section, click Settings.
Step 4: Choose a Dump Type
Look for the Write debugging information drop-down menu. This is the setting that determines what type of memory dump Windows 10 creates after a system failure.
Select one of the following:
- (none)
- Small memory dump
- Kernel memory dump
- Complete memory dump
- Automatic memory dump
- Active memory dump (if available on your build)
Step 5: Review the Dump File Path
Below the drop-down, you can usually see where the dump file will be written. Common locations include:
%SystemRoot%\MEMORY.DMPfor kernel, complete, and automatic dumps%SystemRoot%\Minidumpfor small memory dumps
You can also specify a different path in some cases, which is useful if your system drive is tight on space.
Step 6: Choose Whether to Overwrite Existing Files
If Overwrite any existing file is enabled, Windows will replace the previous kernel or complete dump with the newest one. That is great if you only care about the latest crash. It is terrible if you were hoping to build a crash history and forgot to copy the file first.
Step 7: Click OK and Restart if Needed
Click OK, then click OK again to close System Properties. Restarting is a smart move so the setting is fully in place before the next crash decides to make an uninvited appearance.
How To Change Dump Settings with Command Line or Registry
If you prefer working from the command line, Windows 10 also supports changing recovery settings through command-based methods. For example, different debug info types can be set for none, small, kernel, complete, and automatic dumps. This is especially useful for scripting or configuring multiple machines.
That said, for most people, the graphical method is the safest and easiest because it reduces the odds of changing the wrong value in the registry and accidentally turning your troubleshooting setup into modern art.
Paging File Requirements Matter More Than People Expect
This is the part many users skip, then later wonder why no dump file was created.
A complete memory dump needs a paging file on the boot drive large enough to support it. In practical terms, that usually means a page file at least the size of installed RAM, plus a little extra for the header. Kernel dumps also need enough backing space, though usually less than a complete dump. Automatic memory dump is popular because Windows adjusts the paging file more intelligently when system-managed paging is enabled.
So if you choose Complete memory dump but your paging file is too small, Windows may not be able to write the dump correctly. That is like asking someone to pour a gallon of paint into a coffee mug and then being shocked by the outcome.
Which Dump Type Should You Choose?
Choose Small Memory Dump if:
- You want compact files
- You have limited disk space
- You only need basic crash clues
Choose Kernel Memory Dump if:
- You want a solid balance of detail and storage efficiency
- You are troubleshooting drivers, BSOD loops, or system instability
- You do not need every byte of user-mode memory
Choose Complete Memory Dump if:
- You need maximum diagnostic detail
- You are working with advanced support or debugging tools
- Your system has enough storage and proper paging configuration
Choose Automatic Memory Dump if:
- You want a good default for most real-world troubleshooting
- You prefer Windows to manage paging more automatically
- You want kernel-level data without manually sizing everything
Choose Active Memory Dump if:
- You need richer data than a kernel dump
- You want something smaller than a full complete dump
- You are handling more advanced diagnostic work
Common Problems When Changing Memory Dump Settings
No dump file appears after a crash
Check the paging file size, dump path, and whether the crash type actually triggered dump creation. Also make sure the system rebooted normally after the crash and that cleanup utilities did not remove the file.
The dump file is too large
Switch from complete to kernel or small memory dump. You can also enable overwriting so the system does not keep stacking giant files like digital pancakes.
You cannot find the dump location
Look in C:\Windows\MEMORY.DMP for full-style dumps or C:\Windows\Minidump for minidumps. You can also verify the exact path in Startup and Recovery settings.
The system deletes dump files automatically
Windows may remove memory dumps when disk space is low unless you change that behavior. If you want to preserve crash files for analysis, review the low-disk-space deletion setting and copy important dumps elsewhere before cleanup tools wipe them out.
How To Use the Dump File After You Create It
Changing the dump type is only half the story. Once a crash dump exists, you can analyze it with WinDbg or another supported crash-analysis tool. Small dumps are quick to inspect. Kernel and complete dumps provide more context, especially when trying to isolate driver faults, memory issues, or recurring stop codes.
If you are working with support, they may specifically ask for a minidump, kernel dump, or complete dump. That is why choosing the right type in advance matters. Nobody enjoys having to reproduce a crash just because the computer saved the wrong kind of evidence the first time.
Real-World Examples
Example 1: The home user with a full C: drive
A laptop with 8 GB of RAM keeps generating crash files, and storage is nearly full. In that case, switching to Small memory dump may be the best choice. The user still gets basic crash data without sacrificing gigabytes of storage.
Example 2: The gamer chasing random BSOD errors
If a gaming PC crashes only during heavy GPU load, Kernel memory dump or Automatic memory dump makes more sense. These options provide enough detail to catch likely driver or kernel-level issues without the size burden of a complete dump.
Example 3: The admin troubleshooting a stubborn workstation
An IT admin dealing with recurring workstation crashes may temporarily switch to Complete memory dump or Active memory dump for deeper analysis, then switch back after the root cause is identified.
Experience-Based Advice: What Usually Happens in Real Life
In real-world troubleshooting, people rarely think about memory dump settings until after something has already gone wrong. That is the classic Windows tradition: ignore a technical setting for years, then suddenly become emotionally invested in it at 2:13 a.m. after the third mysterious reboot.
One common experience is discovering that Windows was technically configured to create a dump file, but not the kind that was actually useful. A user might open the Minidump folder and find a few tiny files, only to realize that those files do not reveal enough to diagnose a driver issue. In those situations, switching to a kernel memory dump often becomes the sweet spot. It gives more useful detail without eating the entire drive.
Another common scenario involves storage panic. Someone finds a giant MEMORY.DMP file, assumes it is malware, and contemplates deleting it with the same energy people reserve for spam calls. The truth is less dramatic: the file is usually just Windows doing its job after a crash. But if the computer is stable again and the file is no longer needed, cleaning it up and switching to a smaller dump type can make a lot of sense.
There is also the paging file trap. This one gets even reasonably tech-savvy users. They manually reduce the page file to save space or disable system-managed virtual memory because they read a “speed tweak” article from the internet’s dusty attic. Then Windows crashes and fails to create the complete dump they were expecting. Later, they go hunting for the file like detectives in a procedural drama, only to discover there is no file because the underlying page file settings blocked it.
IT pros often take a more strategic approach. They may leave machines on Automatic memory dump most of the time because it offers a sensible default. Then, when a particular PC becomes the office drama queen and starts crashing every other Tuesday, they temporarily move that machine to kernel or complete dump mode. Once the issue is solved, they scale the setting back down.
There is also a practical lesson many people learn the hard way: if you care about historical crashes, copy the dump files before the next crash or cleanup cycle. Kernel and complete dump files can be overwritten, and low-disk-space cleanup settings can remove dumps automatically. Windows is helpful, but it is not sentimental.
In the end, the best experience-based advice is simple: match the dump type to your goal. If you only want lightweight records, go with minidumps. If you need real troubleshooting muscle, choose kernel or automatic. If you are deep in diagnostic territory, complete or active dumps may be worth the extra size. The smartest setting is not the biggest one. It is the one that gives you useful evidence without creating new problems.
Final Thoughts
Learning how to change the type of memory dump file Windows 10 creates gives you more control over how your system handles serious crashes. It also helps you strike the right balance between storage, convenience, and troubleshooting depth.
If you want the simplest choice for most situations, Automatic memory dump is usually a safe bet. If storage matters most, Small memory dump is the lean option. If you need deeper diagnostics, Kernel, Active, or Complete memory dump settings may be the better fit.
The big takeaway is this: don’t wait until after the next blue screen to decide what kind of crash data you wish you had. Set it now, and let future-you enjoy the rare luxury of being prepared.
