Hello Wntrp,

Thank you for your question and for getting in touch. My name is Samuel and I would be more than happy to help you with your query.

If the issue is not caused by the update, then the Kmode Exception Not Handled error is most likely caused by a driver issue.

You can see "Error: Kmode_Exception_Not_Handled" followed by a name in square brackets. This name is the driver causing the problem and the one we want to update.
Do a search for this driver to find out what hardware it is related to and follow the steps below.

1) Type “Device Manager” in the Windows search bar and click on the corresponding entry.

2) Find the hardware that matches the driver error and right click on it. Choose "Update Driver" from the drop-down menu.

3) When given the option, select "Search automatically for updated driver software" and wait for the process to complete.
If that doesn't work, you can always check the motherboard manufacturer's website for a new driver version, or Google the hardware if the driver belongs to an add-on card or other hardware. If so, download it and run the driver update manually by selecting

4) "Browse my computer for driver software" during the third step.

Also, if the device was updated no more than 10 days ago, you can still return to Windows 10 without losing your files, follow the steps below:

1) Open the “Settings” application, select “System”, look for the “Recover” option and select;

2) In the option “Go back to a previous version of Windows”, click on “Back”;

3) Confirm Microsoft's warnings and the downgrade will start, Wait for the process to finish;
