Yeah, I think that's what you found. I only know it is about remote code execution, but, not knowing it is as serious as you described. I don't mind frequent security patches. But, I really prefer to have new OS not open to big attacks like this.
At least make it hard enough for people to find security holes slower.
Your expectations are unreasonable. Maybe you don't understand that the hole was found in existing code, not code new to Win8? That's the only way I can interpret "make it hard enough for people to find security holes slower." In any case, it is what it is. Microsoft is doing at least as well as everyone else here, and patching rapidly is a good thing that should give you more confidence, not less.
