There are a number of reasons why you could be encountering issues with dnelwf64.sys. Most of the issues concerning sys files involve Blue Screen of Death (BSOD) errors.

That way, it's very easy to restore your system in the unfortunate event you encounter a dnelwf64.sys Blue Screen of Death error after recent changes.
