Manpower and money will not magically fix the problem, you can have an infinite amount of both, it will not help the matter that bugs will always exist in even the most perfect code there is. I'd recommend reading the Mythical Man-Month book if you haven't: https://en.wikipedia.org/wiki/The_Mythical_Man-Month https://en.wikipedia.org/wiki/The_Mythical_Man-Month There is no such thing as a bug-free software. Even if you have a perfect software, the said software can be exploited through the hardware. For an example, DMA attacks, memory attacks, CPU bugs, etc. Intel has one of the most tested validation technologies in the world for their CPUs and they still have bugs in every CPU generation and now with Spectre/Meltdown bugs. Microsoft has in fact been improving their security when they switched to the Security Development Lifecycle, Windows 10 is still more secure than Windows 7 or Vista was but you are talking about 30+ year old OS with a lot of legacy software that they need to harden up. They also cannot change things without breaking the backward compatibility. I personally believe MS is trapped with the backward compatibility promise, it is holding them back but Microsoft has been trying to start over with a new OS via WinRT but it failed, developers are not willing to port software that has less users and users don't want it because it has less apps. It's a chicken and egg issue that Microsoft is still trying to fix with the Desktop Bridge app, supporting Win32/PWA apps in the Microsoft Store.
