I attempted to install the Windows 10 Feature Update v1903, but encountered a blue screen error message saying “System Thread Exception not Handled” and was forced to restart my computer. Fortunately, Windows 10 reverted back to the previous version after the failed update.
Upon investigating the issue in the Event Viewer, I discovered an error message indicating that the update failed with error code 0xC1900101. It appears that the problem may be related to a driver issue, so I went to the manufacturer’s website and installed the latest driver for my Gigabyte B450 Aorus Pro WiFi motherboard and AMD Ryzen 2700x CPU.
However, I am still unable to complete the update and am seeking additional assistance.
Updating your Windows 10 to the latest version is important to keep your computer secure and up-to-date with the latest features. However, sometimes the process can be frustrating, especially when you encounter errors such as the “System Thread Exception not Handled” error during the update process. In this blog post, we will discuss what causes this error and provide you with some solutions to fix it.
What causes the System Thread Exception not Handled error?
The “System Thread Exception not Handled” error occurs when a system thread generates an exception that the error handler does not catch. This error can be caused by a number of factors, including outdated or incompatible drivers, corrupted system files, or hardware issues.
Outdated or incompatible drivers
One of the most common causes of the “System Thread Exception not Handled” error is outdated or incompatible drivers. When you update your Windows 10 to a new version, some of your drivers may become outdated or incompatible with the new version, which can lead to this error.
Corrupted system files
Another possible cause of the “System Thread Exception not Handled” error is corrupted system files. Over time, your system files can become corrupted due to malware infections, software conflicts, or other factors. This can cause your computer to behave erratically and lead to various errors, including the “System Thread Exception not Handled” error.
In some cases, the “System Thread Exception not Handled” error can be caused by hardware issues. This can include problems with your RAM, hard drive, or other components. If you suspect that hardware is causing the error, it’s important to diagnose and fix the issue as soon as possible to prevent further damage to your computer.
How to fix the System Thread Exception not Handled error?
Now that we have identified some of the possible causes of the “System Thread Exception not Handled” error, let’s take a look at some solutions to fix this error.
Update your drivers
As we mentioned earlier, outdated or incompatible drivers can cause the “System Thread Exception not Handled” error. To fix this error, you should update your drivers to the latest version. You can do this manually by going to the manufacturer’s website and downloading the latest driver for your hardware. Alternatively, you can use a driver updater tool to automate the process and ensure that all your drivers are up-to-date.
Run a system file check
If corrupted system files are causing the “System Thread Exception not Handled” error, you can use the built-in System File Checker (SFC) tool to scan and repair your system files. To run an SFC scan, open the Command Prompt as an administrator and type the following command: “sfc /scannow”. This will scan your system files and replace any corrupted files with a cached copy.
Check your hardware
If you suspect that hardware is causing the “System Thread Exception not Handled” error, you should run hardware diagnostics to identify and fix the issue. You can use built-in Windows tools such as the Memory Diagnostic Tool to test your RAM or the Disk Check tool to check your hard drive for errors. If you find any issues with your hardware, you should replace or repair the faulty components.
Disable antivirus software
Antivirus software can sometimes interfere with the update process and cause the “System Thread Exception not Handled” error. To fix this error, you can try disabling your antivirus software temporarily and then running the update process again. Once the update is complete, you can re-enable your antivirus software.
Perform a clean install of Windows
If none of the above solutions work, you may need to perform a clean install of Windows. This will erase all your data and applications, so be sure to back up your important files before proceeding. To perform a clean install of Windows, you will need a Windows installation media, such as a USB drive or DVD. Follow the on-screen instructions to install Windows and then reinstall your applications and drivers.
The “System Thread Exception not Handled” error can be frustrating, but it’s important to identify and fix the issue as soon as possible to prevent further damage to your computer. By following the solutions we have provided in this blog post, you should be able to fix this error and update your Windows 10 to the latest version.

I am providing the answer to my own question. The error code 0xC1900101 in the Event Viewer indicates that driver issues caused the failed update to Windows 10 v1903. To fix this, the next logical step is to update the motherboard’s drivers.
However, upon checking the Gigabyte website for the B450-AORUS-PRO-WIFI motherboard, I found that the latest drivers for Bluetooth and WiFi are only available for Windows 10 v1809. This suggests that the Bluetooth and WiFi drivers may be the cause of the installation issue since they are not compatible with v1903. I cannot confirm this until Gigabyte releases drivers for Windows 10 v1903.
I am sharing this information as a reference for others who may be experiencing similar problems with the Gigabyte B450-AORUS-PRO-WIFI motherboard.
Edit: I have since resolved the issue. Surprisingly, the culprit was the Avast Anti-virus software. After uninstalling it, I was able to successfully upgrade to v1903 and installed all of the latest drivers for the Gigabyte B450-AORUS-PRO-WIFI motherboard available on their website.
