How to resolve the most tenacious Blue Screen error with Windows 10

So at the company I work in, we have had this Blue Screen (SYSTEM_SERVICE EXCEPTION) show up with the file win32kfull.sys mentioned below that code. I have the crash dump, which says

^ This pesky BSOD is affecting 16 computers and here are the steps I have taken so far:

1. Updated all drivers using 'Snappy Driver'. Updated all drivers from official Lenovo on another PC by manually downloading every single one.
2. Ran dskchk, no problems found.
3. Ran DISM (Deployment Image Servicing and Management) command: DISM.exe /Online /Cleanup-image /Restorehealth
4. Updated manually GPU drivers (Integrated Intel) then reverted to older ones too.

None of that has solved this so far. Also, this began solely AFTER the feature update to 1709. And it happens specifically when restarting or signing off. These computers have 8 GB of RAM, and an Intel i5 7500. The model is Lenovo Thinkcentre m710q. Any help is appreciated.
