Many of these types of issues are very difficult to diagnose under the best of circumstances.
In the case of crashes, BSODs, and freezes they may be related to GPU Drivers and these files are being updated very often and are hard to track.
For instance Nvidia has updated it's WHQL driver twice in the last couple days 352.84 and then 352.86

I'm not sure if AMD is currently keep pace or not. I know that various device manufacturers do not seem to be up to date with Windows 10 and consequently I don't know that I would be relying on Windows 10 as an optimal gaming platform at this point in its' progress.
I'm sorry that you are disappointed in the lack of replies and help with respect to Gaming on Windows 10 but.....
Repeating the same banal answer over and over again seems equally disappointing so I suppose many are not prompted to even reply.
Windows 10 is in early stages and full of bugs.
Some people report their games working wonderfully in Windows 10 (usually after chasing down various hardware drivers), while other report, as you have, less than satisfactory results in their experience.
There is some rumor of a new and better build currently in the pipeline for release and hopefully we'll be seeing it soon.
Although I'm not sure that, that will address these types of issues.
