2. Update, Reinstall or Roll Back Drivers

System thread exception not handled is one of the common issues that happen because of faulty or not compatible drivers. So if you have recently updated any of the drivers, then you can roll back them or try updating your existing drivers.

For this, we will again need to enter safe mode. So once you do that, go ahead and follow the below steps:

Update Drivers:

  • Press Windows + X key and go to Device Manager.
  • Now right-click on each and every driver and select Update Driver.
  • Next, Windows will automatically scan for updated drivers and install them for you.

Rollback Drivers:

In case if the error appeared right after updating a driver, then rolling back the driver might fix the issue. To roll back the driver, you have to go to the Device Manager.

Next, navigate to the driver you wish to roll back and, right-click on it, and select Properties.

Then go to the Driver tab and select Rollback driver.

Reinstall Driver:

You can also try reinstalling a driver. For this, you have to go to Device manager -> Select the driver and right-click on it -> Uninstall Driver.
