This update is very interesting because I've been continuing to follow the Nvidia DPC bug and other gaming issues, and inside this latest Microsoft patch are two exciting fixes that I suspected were part of this problem and why the bug is so difficult to figure out. I mentioned them both a few times in those discussions as I started to narrow in on the culprits.
The patch notes I'm talking about say, "This update addresses an issue that might affect your computer when you are playing a game. Timeout Detection and Recovery (TDR) errors might occur." and, "This update affects the Desktop Window Manager (DWM). It improves its reliability."
These fixes are extremely promising because I did months of research and testing on this bug and came to the conclusion that it was a multi-part issue, which is why it couldn't be easily mitigated with a workaround. Part of the problem is on Microsoft's side, which has to do with TDR and DWM (which they started introducing with Vista and beyond), and then part of the problem is Nvidia's drivers.
The number of crashes that happen on Windows has skyrocketed ever since TDR got introduced, so it's always been bugged in my opinion. I saw an infinite number of screenshots and forum posts from people with TDR issues, and it has never been seriously addressed until maybe now. I have a feeling Microsoft looked into this after Nvidia communicated the bug to them and realized that Windows was part of the problem.
Either way, it's a step in the right direction, so hopefully this trend continues and we get more bugfixes of this nature.
