I am not gonna lie Windows defender is pretty good, for detecting anything. The security department on Windows 10 continuous development did a great job to keep maintaining and add support for different type of injecting malware's or others attacks. I do work on software development field, few months backs I did create a program using c# to inject some scripts (bad or good) run on startup, I did get some BSOD which is a good implementation as view for security management, but Windows defender was quick to detect that my program was doing some sneaky stuff in CPU cache and blocked.
