What does a stop code look like? What are common Windows stop code errors? How to find and fix Windows stopcode on your Windows 11/10/8/7 PC? In this post, MiniTool shows you the detailed answers to these questions and let’s continue reading.

What Is Windows Stopcode

Sometimes your PC suddenly crashes and the safest thing the PC can do is to stop everything and then restart.  When this occurs, you can see a blue screen error and stop code on the computer screen. The Windows stopcode error contains some handy information.

What does a stop code look like? A Windows stop code, also called a bug check or bug check code, is a unique number that identifies a specific stop error (Blue Screen of Death – BSOD). The Windows stopcode is displayed in the hexadecimal format that starts with 0x, followed by an eight-character string.

Windows stopcode can also be written in a shorthand form, for example, 0xc000021a – called 0x21a. You see all the zeros after the x are removed.

All the Windows 11/10 stop codes are different from each other and every one refers to a unique Windows error that instructs you on how to assist in fixing the malfunction. Most stop codes are related to device drivers, RAM, and other hardware or software issues.

Common Windows Stop Code Errors

As mentioned above, each Windows stopcode indicates a stop error. In Windows, there are many stop codes and let’s see some common ones.

Windows Stopcode	Stop Error	Explanation
0x0000001A	MEMORY_MANAGEMENT	a severe error with system memory management
0x0000003B	SYSTEM_SERVICE_EXCEPTION	an exception happened while executing a routine that transitions from non-privileged code to privileged code
0x000000EF	CRITICAL_PROCESS_DIED	a critical system process died
0x000000ED	UNMOUNTABLE_BOOT_VOLUME	the I/O subsystem attempted to mount the boot volume and failed
0x0000012B	FAULTY_HARDWARE_CORRUPTED_PAGE	a hardware memory error
0x0000007B	INACCESSIBLE_BOOT_DEVICE	OS fails to access the system partition during startup
0x00000074	BAD_SYSTEM_CONFIG_INFO	an error in the registry
0x00000019	BAD_POOL_HEADER	a pool header is corrupt
0xC0000221	STATUS_IMAGE_CHECKSUM_MISMATCH	a driver or a system DLL has been corrupted
0xC000021A	STATUS_SYSTEM_PROCESS_TERMINATED	it happens when a critical process (winlogon.exe or csrss.exe) fails
0x0000009A	SYSTEM_LICENSE_VIOLATION	the software license agreement has been violated

This table only lists some common Windows stopcode errors and if you want to know a complete list, see this guide from Lifewire – List of Blue Screen Error Codes (from stop 0x1 to STOP 0xC0000225). If you are using a Windows 10/11 PC, you can refer to our related post – Your PC Ran into a Problem and Needs to Restart to find some common stop errors.

How to Fix Windows Stopcode Errors Windows 11/10/8/7

After knowing so much information about Windows stop codes, if you suffer from a blue screen error along with a stop code, how can you fix it?

Sometimes the blue screen also shows you a message to ask you to contact www.windows.com/stopcode. This link brings you to a page on resolving blue screen errors in Windows. For a specific stop error, the fixes are a bit different but some common basic troubleshooting tips can help a lot. Now, let’s go to see some you can try.

Back up Your Important Files (Suggestion)

Sometimes blue screen errors keep appearing randomly and may bring severe results – your files lose after a stop error. So, if you meet a frustrated Windows stopcode in Windows 11/10/8/7, we strongly suggest that you should create a backup for your important files at once.

To do this thing, running a piece of professional backup software is a good choice. In Windows, the inbuilt utility – Backup and Restore can help a lot in data backup. But it has a limitation – it doesn’t allow us to select individual files to back up but choose folders. Besides, this tool is not flexible and you often suffer from a failed backup.

To back up your files well, using the third-party PC backup software like MiniTool ShadowMaker is a good choice. This tool supports file backup, disk backup, partition backup and system backup. To automatically back up your data, you can configure a schedule plan. Also, you can make incremental backups and differential backups with this tool.

Importantly, MiniTool ShadowMaker allows you to create a bootable USB drive so that you can back up your computer in case of system crashes. Now, get its trial edition via the following button and then start a data backup in case of Windows stopcode.

Step 1: Connect an external drive to your PC and run MiniTool ShadowMaker Trial Edition to enter its main interface.

Step 2: Tap on Backup > SOURCE > Folders and Files, then open your computer to find and select the items you need to back up and click OK.

Step 3: Choose an external drive to save the backup image.

Step 4: Tap on Back Up Now to execute the file backup.

Next, start Windows stopcode fixes. Note that the following fixes are done in the Windows desktop version. If your machine fails to boot, you can perform these troubleshooting tips in Safe Mode. Don’t know how to enter this mode? Follow the guide – How to Start/Boot Windows 11 in Safe Mode? (7 Ways) and choose a proper way.

Restart Your Computer

Restarting your laptop or desktop is the easiest and simplest thing that you can try to solve a Windows stop error. Sometimes a reboot can do the trick. Just press and hold the power button for 10 seconds to turn off the PC.

Then, disconnect all the external devices including external hard disks, USB flash drives, printers, webcams, and SD cards.  If you are using a laptop, disconnect the AC adapter or power cable and remove the battery. Wait a while, put the battery back and power on the machine, then connect your devices to the PC and see if BSOD errors happen.

If this way is ineffective, try other ways to address stop codes in Windows 11/10/8/7.

Run SFC & DISM and CHKDSK

In many cases, the Windows stopcode error may be caused by corrupted system files, some file system errors and hard disk errors. You can try to fix the corruption or these errors by using the Windows system utilities – SFC, DISM and CHKDSK.

SFC, short for System File Checker, helps to scan the entire operating system for the system files. If it detects corrupted files in the system, it can replace the corruption.  How to run an SFC scan for fixing broken system files? See the steps.

Step 1: Press Win + R, type cmd into the textbox and press Ctrl + Shift + Enter to run Command Prompt with admin rights. If prompted by the UAC window, click Yes.

Step 2: Type sfc /scannow and press Enter. Then, this tool starts the scan process.

Usually, we also run a DISM scan using the Deployment Image Servicing and Management tool to fix Windows bad images in addition to SFC. In the CMD window, run the command – DISM /Online /Cleanup-Image /RestoreHealth.

Next, run the CHKDSK scan to check and repair file system errors and hard drive errors that may lead to a stop code in Windows 11/10/8/7. In the CMD window with admin rights, run the command – chkdsk x: /f /r. Replace x with the letter of your drive.

Update Windows

When Windows stopcode errors happen on your PC, you can try to update the operating system. This is because Windows updates may include bug fixes and patches for some known issues besides security updates. If you are using Windows 10/11 PC, follow these instructions to keep Windows up-to-date.

In Windows 10, go to Settings > Update & Security > Windows Update, and then check for available updates. If some are found, download and install them. In Windows 11, go to Settings > Windows Update to update Windows to the latest version.

Uninstall Incompatible Updates, Apps or Drivers

Sometimes a recently-installed Windows update, app or driver can cause a Windows stopcode error on the blue screen. To fix BSOD in Windows 11/10, go to uninstall them.

To uninstall an update in Windows 10, go to Settings > Update & Security > Windows Update > View update history > Uninstall updates. In Windows 11, go to Settings > Windows Update > Update history > Uninstall updates. Next, choose the recent update and click Uninstall.

To uninstall a driver or app, go to Control Panel > Uninstall a program under Programs (viewed by Category), choose the target item and click Uninstall.

Perform a System Restore

If you have a restore point created before Windows stopcode errors happen, you can use that point to bring the Windows system to a previous good state. System Restore is a good option to undo some changes to revert your PC to an earlier state.

Step 1: Type create a restore point into the search box and open the System Properties window.

Step 2: Tap on System Restore.

Step 3: After choosing a restore point based on the created time, click Next > Finish.

These are the common Windows 11/10 stopcode fixes that you can try. In addition to these workarounds, you can try some other ways. And you should search for the specific stop code error online and find out the detailed solutions.

Final Words

That’s all the basic information about Windows stopcode including what it looks like, some common Windows stop codes, how to find and fix Windows stop errors on your PC. Blue screen of death is a royal pain for many users over the decades. Hopefully, this guide here can help you better understand the blue screen errors.

This guide walks you through the various stop codes, what they mean, and their causes.

You have probably heard recent news stories about the thousands of Windows PCs booting up with a blue screen of death , disrupting the operation of supermarkets, banks, airlines, and many other businesses worldwide. Even though it wasn’t Microsoft’s fault, it shows how problematic BSODs can be. 

Data loss, system instability, and serious work disruption are some of the issues that can result from BSODs. Fortunately, BSOD errors usually come with a W indows stop co de, which can help you identify the problem and resolve it before it gets worse. 

I’ll walk you through everything important you need to know about stop codes and how to use them to resolve various BSODs issues. 

Let’s begin.

What Is a Windows Blue Screen of Death?

BSODs (blue screen of death), or STOP codes, alert users about critical system failures that force Windows to crash. They appear on blue backgrounds (hence the name) and typically do not linger for long before the system restarts.
Every Windows blue screen may look similar, but each error displays a message with the name of the affected file and a code (called a bug check value) to explain the cause of the problem. The operating system saves a dump (.dmp) file with more details about the crash on your system before rebooting.
Earlier BSOD errors threw a lot of vague information and code at users, which left most of us even more confused. But since Windows 8, Microsoft has scaled back the texts and tried to make the screen less scary and more helpful.
Stop code interfaces now contain QR codes, stop code descriptions that you can look up on Microsoft’s website, and sad smiley faces.

What Causes the Blue Screen of Death?

I mentioned that Windows saves a dump file before rebooting. Reading and interpreting these .dmp files can help explain the causes of the BSOD error. Going through the Windows Event Viewer is another way to find the specific cause of the problem.

Still, the following underlying issues should come to mind whenever Windows displays a blue screen:

• Device driver issues

Device drivers act as go-betweens for Windows and your hardware. BSODs show up when these drivers are out-of-date, corrupt, or missing.  

• Faulty hardware

Some stop codes advise you to check recently installed hardware devices because blue screens of death on Windows 10 and Windows 11 are generally connected to hardware issues. A recently installed device or an older component might be malfunctioning and triggering the error. They include your RAM, hard drive, and peripherals.

• Missing and damaged system files

System files control critical Windows processes, from boot operations to shutdowns. If any of these files are missing or corrupt, Windows will experience a fatal failure that will cause the blue screen error.

• Malware

Malicious programs can corrupt or delete system files and drivers to trigger BSOD errors.

• Overheating

Windows usually displays blue screens and shuts down when system temperature reaches dangerous levels. I got used to blue screens when I put my gaming laptop under load and it generated too much heat. The solution was employing effective cooling measures. Your overheating issue could be due to a poor cooling system, your computer activity, or unsafe overclocking .

Different Microsoft Stop Codes and What They Mean

The first step to fixing a blue screen of death issue is to understand the stop code you are seeing and the potential cause of the error. Different stop codes warn you about different things and have different severity levels. The following is a list of some of the Windows stop codes and what they mean:

Method 1: Using the Event Viewer to check stop codes

While Wi ndows stop code s can be helpful, they often don’t provide a complete picture. To truly understand the causes of the BSOD, you need to dig a bit deeper. This is where the Event Viewer comes in. 

It’s a built-in log viewer that records everything under your system’s hood. Event Viewer is your first stop when deciphering what causes the BSOD. Follow these steps to check stop codes: 

• Press the Windows key to open the Start menu, type  “Event Viewer,”  and select it.

• In the Event Viewer, look at the left panel and click  Windows Logs  category.

• Under  Windows Logs , click on  System.  System logs carry detailed records of your system’s operations, including Microsoft stop code occurrences.
