As a Windows user, you probably never look forward to encountering BSOD (Blue Screen of Death) errors because many are quite serious and require much time to fix. However, other BSOD errors, like the Kmode Exception Not Handled Error are quite easy to troubleshoot if you know what to look for.

The Kmode Exception Not Handled Error is a common error affecting many Windows users, and this problem results when programs conflict with each other, leading to errors and crashing software. Whatever the reason, this guide will give you some effective ways to fix this problem.

1. Disable Fast Startup

Windows Fast Startup could cause this problem. This feature enables quick recovery from shutdown and hibernation, but it can also result in the loading of any previous driver issues. Disabling Fast Startup frequently prolongs the duration of your system’s uptime or perhaps resolves the issue completely.

  1. Launch the Search bar by pressing Windows + S, then type Control Panel and choose the required option.
