Thought to share my experience with applying the Intel SA-00086, Spectre, Meltdown patch (MEUpdate_D0_H_V2.0.0.4) to my G752VY.
Before the update I ran PC Mark 10 benchmark (and not any other) to see if there would be a performance difference in day-to-day use. The results did not give an indication (The test after the update was even better than the test before the update). But then the problems started. After the update I updated some other software on my notebook which required a reboot. When Windows (the latest FCU/1709 update) restarted I got a blue screen with an INACCESSIBLE_BOOTDEVICE error. I was able to use system restore to get up and running again but with new reboots I kept having this issue and in the end I was not even able to use system restore anymore and I was locked out of the OS.
I did a full reset with preservation of files and that brought me back into the system.
I did not dig deep into the problems just yet but I feel that it had to do with my RAID0 setup (2x Samsung 950 Pro 1TB) causing the issues. Another thing that occurred is an extremely long boot time. Almost 9 minutes from powerswitch to Win 10 start screen.
If I find a why or a solution I'll get back here. Maybe someone has already tackled this problem, then please share the solution. And if no one has this problem then my G752 is maybe at fault.
