Fix – SYSTEM THREAD EXCEPTION NOT HANDLED M Windows 10 error

Solution 1 – Update Windows 10 and install the latest drivers

Windows 10 has a few errors with certain hardware and software, and in order to fix these errors it’s important that you update Windows 10. Microsoft is aware of these issues, and it’s trying to fix them with latest Windows 10 updates. In addition to bug fixes, new updates also bring new features and security improvements, therefore if you want your PC to be stable and free from errors, we strongly advise to use Windows Update and download the latest patches.

In addition to downloading the latest patches, it’s also important to have the latest drivers installed. Windows 10 relies heavily on drivers in order to work with your hardware, and if your drivers are outdated or just not fully compatible with Windows 10, you might get SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M BSoD error. To prevent these errors from appearing it’s important that you keep your drivers up to date. Updating your drivers is fairly simple, and you can do it simply by visiting your hardware manufacturer’s website and downloading the latest drivers for your device.

Users reported that updating Nvidia or AMD graphic card driver fixed the issue for them, so be sure to update those drivers first. Few users also reported issues with Qualcomm Atheros wireless adapter drivers, so if you’re using the aforementioned adapter, make sure to install the latest drivers for it. If updating those drivers doesn’t fix the issue, update all drivers on your system.

Update drivers automatically

Searching for drivers on your own can be time-consuming. So, we advise you to use a tool that will do this for you automatically. Using an automatic driver updater will certainly save you from the hassle of searching for drivers manually, and it will always keep your system up to date with the latest drivers.

Tweakbit’s Driver Updater (approved by Microsoft and Norton Antivirus) will help you update drivers automatically and prevent PC damage caused by installing the wrong driver versions. After several tests, our team concluded that this is the best-automatized solution.

Here is a quick guide on how to use it:

  1. Download and install TweakBit Driver Updaterdriver updater starting window
  2. Once installed, the program will start scanning your PC for outdated drivers automatically. Driver Updater will check your installed driver versions against its cloud database of the latest versions and recommend proper updates. All you need to do is wait for the scan to complete.

To update one driver at a time, click the ‘Update driver’ link next to the driver name. Or simply click the ‘Update all’ button at the bottom to automatically install all recommended updates.

    Note: Some drivers need to be installed in multiple steps so you will have to hit the ‘Update’ button several times until all of its components are installed.

Solution 2 – Run the BSOD Troubleshooter 

The next thing we’re going to try here is Windows 10’s built-in troubleshooting tool. This tool is designed to deal with all kinds of system issues, so it might be helpful with the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M error, as well.

Here’s how to run Windows 10’s troubleshooting tool:

  1. Open Settings app.
  2. Go to the Update & Security section, and select Troubleshoot from the menu on the left.
  3. Select BSOD from the right pane and click Run the troubleshooter.SYSTEM THREAD EXCEPTION NOT HANDLED M
  4. Follow the further instructions on the screen to complete the troubleshooter.

Solution 3 – Run the SFC scan

The SFC scan is another troubleshooting tool we’re going to try. This is a command-line scanning tool that scans your computer for potential issues, and resolves them along the way. A lot of users have reported that the SFC scan can be useful when dealing with BSOD issues in Windows 10.

Here’s how to run the SFC scan in Windows 10:

  1. Right-click on the Start Menu button, and open Command Prompt (Admin).
  2. Enter the following line and press Enter: sfc/scannowSYSTEM THREAD EXCEPTION NOT HANDLED M
  3. Wait until the process is done (it may take a while).
  4. If the solution is found, it will automatically be applied.
  5. Now, close the Command Prompt and restart your computer.

Solution 4 – Run DISM

And the third troubleshooting tool we’re going to try is DISM. Deployment Image Servicing and Management (DISM), as its name says, re-deploys the system image, and resolves potential issues along the way. So, it could also resolve the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M error.

We’ll walk you through both standard and the procedure that utilizes the installation media below:

  • Standard way
  1. Right-click Start and open Command Prompt (Admin).
  2. Paste the following command and press Enter:
      • DISM /Online /Cleanup-Image /RestoreHealthSYSTEM THREAD EXCEPTION NOT HANDLED M
  3. Wait until the scan is finished.
  4. Restart your computer and try updating again.
  • With the Windows installation media
  1. Insert your Windows installation media.
  2. Right-click the Start menu and, from the menu, choose the Command Prompt (Admin).
  3. In the command line, type the following commands and press Enter after each:
    • dism /online /cleanup-image /scanhealth
    • dism /online /cleanup-image /restorehealth
  4. Now, type the following command and press Enter:
    • DISM /Online /Cleanup-Image /RestoreHealth /source:WIM:X:SourcesInstall.wim:1 /LimitAccess
  5. Make sure to change an X value with the letter of the mounted drive with Windows 10 installation.
  6. After the procedure is finished, restart your computer.

Solution 5 – Check the hard drive

If your hard drive is damaged, BSOD issues are more than possible. To eliminate the doubt, you should run the chkdsk, which scans all your partitions, and resolves potential problems (if possible). So if the culprit of the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M is a corrupt hard drive, this tool will likely resolve the problem.

Here’s how to run the chkdsk command in Windows 10:

  1. Enter the Advanced Startup (Restart your computer while holding the Shift key).
  2. Choose Troubleshoot > Advanced Options.
  3. Select Command Prompt from the list of options.
  4. When Command Prompt appears, enter the following lines and press Enter after each line in order to run it:
    • bootrec.exe /rebuildbcdSYSTEM THREAD EXCEPTION NOT HANDLED M
    • bootrec.exe /fixmbr
    • bootrec.exe /fixboot
  5. Some users are also suggesting that you need to run additional chkdsk commands as well. To perform these commands, you need to know drive letters for all your hard drive partitions. In Command Prompt you should enter the following (but remember to use the letters that match your hard drive partitions on your PC):
    • chkdsk /r c:
    • chkdsk /r d:

    This is just our example, so keep in mind that you have to perform chkdsk command for every hard drive partition that you have.

  6. Restart your computer and check if the issue is resolved.

Solution 6 – Remove your antivirus software

Antivirus software is crucial for your system’s safety, but sometimes your antivirus software can cause these types of errors to appear. To fix SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M and many other BSoD errors, it’s important that you temporarily remove your antivirus software. Bear in mind that by removing your antivirus software you won’t be completely defenseless because Windows 10 comes with Windows Defender that works as a default antivirus program. To completely remove certain antivirus from your PC, it’s recommended that you use a dedicated removal tool. Almost all antivirus companies have these tools available on their websites, so be sure to download one of these tools for your antivirus software.

Users reported that Norton and McAfee are the cause for this error, but bear in mind that almost any antivirus program can cause this error to appear, so be sure to remove all third-party antivirus programs from your PC. If removing your antivirus fixes the problem, you can now reinstall it or you can switch to a different antivirus solution.

Solution 7 – Remove problematic applications

Even though your antivirus is the common cause for BSoD errors, almost any third-party application can cause SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M error to appear. To fix this problem, be sure to remove any recently installed or updated applications.

According to the users, MSI Afterburner, RealTemp, UltraISO and SoundTap Streaming Audio Recorder can cause this error to appear, therefore if you’re using any of these applications we strongly suggest that you remove them.

Solution 8 – Reset your BIOS

If your BIOS isn’t properly configured, you might get SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M or any other Blue Screen of Death error. To quickly fix this problem you just need to enter BIOS and reset it. By resetting BIOS all your settings will be reverted to default, thus fixing the BSoD error. To see how to enter BIOS and how to reset it, we strongly advise that you check your motherboard manual for detailed instructions.

Solution 9 – Reset Windows 10

If the SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M error is caused by certain software, you can fix it easily by performing a Windows 10 reset. We should warn you that this process is similar to clean install, therefore we suggest that you back up your important files. To complete Windows 10 reset you might also need a bootable USB flash drive with Windows 10 on it, so be sure to create one. To perform Windows 10 reset follow these steps:

  1. Restart your PC few times during the boot sequence to start the Automatic Repair.
  2. Select Troubleshoot > Reset this PC > Remove everything. Insert Windows 10 installation media if you’re asked to.
  3. Choose Only the drive where Windows is installed > Just remove my files and click the Reset button to start the process.
  4. Follow the instructions on the screen to complete the reset.

After you complete Windows 10 reset, don’t install any software or drivers, instead test if your PC is working properly. If the error appears again, it means that your hardware is causing it.

Solution 10 – Check for faulty hardware

Hardware can be the common cause for BSoD errors, especially if it’s not compatible with your PC. If you installed any new hardware recently, we strongly suggest that you remove it or replace it and check if your PC works well without it. If the problem isn’t caused by new hardware, we strongly advise that you perform a detailed hardware inspection in order to find and replace the faulty hardware.

If you’re still having issues with your hardware or you simply want to avoid them for the future, we recommend you to download this tool (100% safe and tested by us) to fix various PC problems, such as hardware failure, but also file loss and malware.

SYSTEM_THREAD_EXCEPTION_NOT_HANDLED_M error isn’t as serious as other Blue Screen of Death errors, and you can easily fix it by updating your drivers or by removing the problematic software.
