KMODE_EXCEPTION_NOT_HANDLED (wdf01000.sys)

Please run driver verifier again using the settings from the driver verifier tutorial in post KMODE_EXCEPTION_NOT_HANDLED (wdf01000.sys) - Windows 10 Forums

 

BSOD KMODE_EXCEPTION_NOT_HANDLED

The stop code is KMODE_EXCEPTION_NOT_HANDLED (1e), which is an uncaught exception. The stack does not indicate the signs of any 3rd party driver, but the frame starts in NDU.sys, the Windows Network Data Usage Monitoring Driver. Based on the function NduInboundMacClassify
we can assume it is doing some MAC type routine for the network adapter before bugcheck is reached:

If we dump the thread, we see entry of Realtek network adapter, rt640x64.sys:

ffff9280`a967e3c0 ffffbc01`e1eaf000

However, we also have presence of another component, cfosspeed6.sys:

ffff9280`a967e338 fffff806`34f51143 fwpkclnt!FwppNetBufferListEventNotify+0x103

cfosspeed6.sys looks to be a component of cFosSpeed, which looks like an internet speed accelerator:
Product Overview - cFos Software. My guess is that this is culprit for the bugcheck. I hope you did not spend money on this because my obvious suggestion is to remove it.

 

KMODE_EXCEPTION_NOT_HANDLED on igdkmd64.sys

My computer keeps giving me the blue screen of death and giving me error code

KMODE_EXCEPTION_NOT_HANDLED on igdkmd64.sys

How can this be fixed?
