If you encountered an error message that says, “Unhandled exception has occurred in your application”, when you start your Windows 10 computer, read on as this post will guide you on how you can fix it. This kind of error usually appears in a Microsoft .NET Framework window and it mostly pops up as soon as you turn on your computer. Here’s the complete context of the error message:

“Unhandled exception has occurred in your application. If you click Continue, the application will ignore this error and attempt to continue. If you click Quit, the application will close immediately.”

When this error occurs, your computer may freeze or display other suspicious behavior at times. Either way, there are several options you can check out in this post to resolve this issue, so read on. This kind of error could be caused by several factors. It could be due to your antivirus program or other third-party programs installed on your computer. It is also possible that the installation of the Microsoft .NET framework id corrupted or some of its installation files are corrupted. Thus, to fix the error, there are a few suggestions you need to follow such as:

Option 1 – Try to temporarily disable your anti-virus program

As mentioned, the error could be due to the antivirus program or the Windows Defender Firewall installed on your computer. Thus, disabling them or any security software installed in your computer is always a good idea you can try when you’re not able to access the shared drive in your computer. There are times when you encounter problems like the “Unhandled exception has occurred in your application” error due to interference of antivirus or security programs. Thus, you have to disable both your antivirus program in the meantime and check if it fixes the error or not.

Option 2 – Put your computer in a Clean Boot State

As pointed out, it is possible that some third-party program or service is the one that’s behind the problem. To isolate this possibility and to identify the culprit, you have to put your computer into a Clean Boot State. To do so, follow the steps below.

• Log onto your PC as an administrator.
• Type in MSConfig in the Start Search to open the System Configuration utility.
• From there, go to the General tab and click “Selective startup”.
• Clear the “Load Startup items” check box and make sure that the “Load System Services” and “Use Original boot configuration” options are checked.
• Next, click the Services tab and select the “Hide All Microsoft Services” check box.
• Click Disable all.
• Click on Apply/OK and restart your PC. (This will put your PC into a Clean Boot State. And configure Windows to use the usual startup, just simply undo the changes.)
• Once your computer has restarted, check if the error is now gone. If it is, then the culprit is some third-party program. Thus, you have to enable the third-party programs one by one to find out which one of them is causing the the “Unhandled exception has occurred in your application” error.

Option 3 – Try to run a System File Checker scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files that might be the cause why you’re getting the “Unhandled exception has occurred in your application” error. To run the SFC command, follow the steps given below.

• Type “cmd” in the Start search and then right-click on the appropriate search result.
• Next, select “Run as administrator” to open Command Prompt with admin privileges.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Now restart your computer and see if the problem is fixed or not.

Option 4 – Install and update Dependencies

There are times when programs and applications need to have drivers and supporting software installed for them to properly work. Although the installation usually takes care of it, it’s time for you to do some manual check especially if you are getting this issue of abnormal program termination.

• Install some qualified drivers – A number of high-end games and applications need to have correct and valid drivers for them to work. They just don’t work with general drivers though. Microsoft has this Windows Hardware Quality Labs testing also known as WHQL testing which makes sure that drivers meet the correct experience and pass through the proper testing before certification. Thus, when installing drivers, you need to ensure that they are qualified drivers for your Windows 10 PC.
• Download and install or Update DirectX – As you know, Microsoft DirectX is a suite of technologies developed by Microsoft to provide hardware acceleration for heavy multimedia applications like HD videos and 3D games. Since you are using Windows 10, you have the DirectX 12 version while the earlier Windows versions use the DirectX 11 version.
• Install the Microsoft DirectX End-user runtime – The Microsoft DirectX end-user runtime gives updates to version 9.0c as well as previous versions of DirectX. To install it, click on this link and download it.
• Update or install the .NET framework – The .NET framework is used by games and applications during development which means that without the runtime files that are installed in your computer, it definitely won’t work. Thus, you need to install or update this framework. You can also use the .NET setup verification tool to verify it.

Windows 11 is coming soon, from its typical view and color scheme, Windows 11 will natively support dark mode. The dark mode is very popular in many applications today, some large companies like Adobe, Autodesk, and many more have already adopted a dark color scheme for their software so it is logical for others to follow and Microsoft is aboard for it. The dark mode itself has its benefits, for people who work on computer for longer period of time dark mode inside applications will throw less white and blue light on their eyes making workhours easier and pleasant on them. As a person who does indeed spend a lot of time in front of the screen, I would advise you to switch to dark mode regardless of the time that you spend with a computer, your eyes will be grateful.

Switching to Dark mode in Windows 11

1. Open Windows 11 Settings by pressing ⊞ WINDOWS + I
2. Click on Personalization on the left sidebar
3. On the right side click on Color
4. In color options click on the drop-down menu right next to Choose your color

Athwbx.sys or the Qualcomm Atheros driver file is known to trigger several Blue Screen of Death errors. This occurs when the driver gets corrupted or when the operating system is unable to access or find it. In addition, bad sectors in the hard disk or RAM can also cause BSOD errors. The athwbx.sys file is known to cause the following BSOD errors listed below:

• SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (athwbx.sys)
• STOP 0x0000000A: IRQL_NOT_LESS_EQUAL (athwbx.sys)
• STOP 0x0000001E: KMODE_EXCEPTION_NOT_HANDLED (athwbx.sys)

If System Restore didn’t help in fixing the Blue Screen error, now’s the time for you to resort to the troubleshooting tips provided below but before you get started, make sure that you create a System Restore point first.

Option 1 – Try recreating the athwbx.sys file

The first thing you can try is to recreate the athwbx.sys file. Every time your Windows 10 PC boots up, it looks for all the system drivers in place and if it is unable to find them, it tries to create them. This is why if you remove your corrupt driver file, chances are, you might get a fixed file recreated just for you. How? Refer to the steps below.

• Boot your Windows 10 PC in Safe Mode.
• Then open File Explorer and navigate to this location: C:/Windows/System32/drivers

Option 2 – Try to update or rollback your device drivers

If the first option didn’t work for you, then it’s time to either update or roll back the device drivers. It is most likely that after you updated your Windows computer that your driver also needs a refresh. On the other hand, if you have just updated your device drivers then you need to roll back the drivers to their previous versions. Whichever applies to you, refer to the steps below.

• Open the Devices Manager from the Win X Menu.
• Then locate the device drivers and right-click on them to open the Properties.
• After that, switch to the Driver tab and click on the Uninstall Device button.
• Follow the screen option to completely uninstall it.
• Finally, restart your computer. It will just reinstall the device drivers automatically.

Note: You can install a dedicated driver on your computer in case you have it or you could also look for it directly from the website of the manufacturer.

Option 3 – Run the System File Checker Scan

System File Checker or SFC is a built-in command utility that helps in restoring corrupted files as well as missing files. It replaces bad and corrupted system files with good system files. To run the SFC command, follow the steps given below.

• Tap Win + R to launch Run.
• Type in cmd in the field and tap Enter.
• After opening Command Prompt, type in sfc /scannow

The command will start a system scan which will take a few whiles before it finishes. Once it’s done, you could get the following results:

1. Windows Resource Protection did not find any integrity violations.
2. Windows Resource Protection found corrupt files and successfully repaired them.
3. Windows Resource Protection found corrupt files but was unable to fix some of them.

• Restart your computer.

Option 4 – Try to run the CHKDSK utility

Running the CHKDSK utility might also help you resolve the athwbx.sys Blue Screen error. If your hard drive has issues with integrity, the update will really fail as the system will think that it’s not healthy and that’s where the CHKDSK utility comes in. The CHKDSK utility repairs hard drive errors that might be causing the problem.

• Open Command Prompt with admin privileges.
• After opening Command Prompt, execute the following command and hit Enter:

chkdsk /f /r

• Wait for the process to be completed and then restart your computer.

Option 5 – Run the Memory Diagnostic Tool

Running the Windows Memory Diagnostic tool in Windows 10 might also help you in fixing the athwbx.sys Blue Screen error. Refer to the steps below on how to run this tool:

• Tap the Win + R keys to open Run and type exe and hit Enter to open the Windows Memory Diagnostic Tool.
• After that, it will give two options such as:
  • Restart now and check for problems (Recommended)
  • Check for problems the next time I start my computer
• Once your computer has restarted, perform a basic scan or you could also go for the “Advanced” options such as “Test mix” or “Pass count”. Simply tap the F10 key to start the test.

Note: After you select the option, your PC will restart and check for memory-based issues. If it finds any issues, it will automatically fix them and if there’s no issue found, then it’s most likely not a memory-based issue so you should try the other options given below.

Option 6 – Run the Blue Screen Troubleshooter

The Blue Screen troubleshooter is a built-in tool in Windows 10 that helps users in fixing BSOD errors like athwbx.sys. It can be found on the Settings Troubleshooters page. To use it, refer to these steps:

• Tap the Win + I keys to open the Settings panel.
• Then go to Update & Security > Troubleshoot.
• From there, look for the option called “Blue Screen” on your right-hand side and then click the “Run the troubleshooter” button to run the Blue Screen Troubleshooter and then follow the next on-screen options. Note that you might have to boot your PC into Safe Mode.
