Fix Windows 10 error KMode Exception Not Handled
There are two ways to address this STOP error, both are relatively straightforward to achieve. The first is to disable fast startup and the other is to update the driver in question.
If you’re stuck in a reboot loop, use the installation media to access Advanced Startup. Read this tutorial if you need help.
1. Navigate to Control Panel, System and Security and Power Options.
2. Select ‘Choose what power buttons do’.
3. Click ‘Change settings that are currently unavailable’.
4. Uncheck the box next to ‘Turn on fast start-up’ and Save changes.
Fast startup is a sort of hybrid shutdown and hibernate mode that isn’t without its problems. One of them is issues with loading drivers.
If that doesn’t work, try updating the driver mentioned in the error text. The error will read similarly to ‘Error: KMODE_EXCEPTION_NOT_HANDLED (DRIVER.sys)’ As mentioned above, where I put DRIVER, you will see another filename. We can use that to update your system.
Perform a search on the filename you’re seeing in your error text to find out what driver it relates to.
1. Navigate to Control Panel, Hardware and Sound, Device Manager.
2. Find the hardware in question, right click and select ‘Update Driver Software’.
3. Reboot your computer if directed to.
Hopefully, that will fix the error!
