BSOD upgrading to Insider 14942

[CowboyGeek]

Experienced the same:

Upgrading to build 14942, all would go well until it was time for the desktop to load and then I would get a BSOD. The error would occur at loading "mwac.sys" This is a software driver for Malwarebytes. Disabled the service from startup and all is good.

Sorry for the delay, I have not used or launched Malwarebytes sense the upgrade due to it causing BSOD. Holding out for a fix. Anyway here the the files you requested.

Hello.
I was doing some casual reading today about the Windows Insider Preview builds today.
Looking at MS Windows Blog article announcements about Preview build 14946
https://blogs.windows.com/windowsexperience/2016/10/13/announcing-windows-10-insider-preview-build-14946-for-pc-and-mobile/
I would call attention to this line in the section titled "Known issues for PC"

If you have 3rd party antivirus products such as Bitdefender, Kaspersky Antivirus, F-Secure Antivirus and Malwarebytes installed on your PC – your PC might not be able to complete the update to this build and roll-back to the previous build.

All builds 149xx  ( or later) are test previews.  Y M M V as the saying goes.  Your mileage may vary.
My recommendation is to see if you can revert back to an earlier build version.
Otherwise, revert back to a current release from the Current Branch.  The current one is version 1607 Build 14393.321

imho, that notation from MS means that that build is not ready for prime time.  It is also not a "release" but a test "preview".  The note means that MS is aware of the issue.
Wait for a fixed version before going back to these preview builds.
There are lots of others having issues with the last sets of preview builds, including at least 2 other preceding this one.  That also includes BSOD issues like yours here.
