I understand your grief. The problem is totally unacceptable.
If you had the BSODs since last week (around Feb 14) then it's almost certain that cause is the 2778344 update. But for you and some other people who started getting the BSODs as far back as last December, or this January, then the update is certainly not the cause (because it didn't exist at that time yet).
I find it hard to believe that new machines that have just been bought can have hardware faults. It should have been software fault. And so, by trial-and-error, maybe you can figure out what piece of software that caused it. It takes a lot of patience, I know. But some times it's worth it in the end.
