Sorry man to disturb your thread... Because people/users wants to disable it until they don't need it, but M$ will turn it on back after about half of the hour (or so) without asking or informing the user. So, you don't have the control over your personal computer, because someone from M$ decide for you (I don't know why people allows for this and that). @ExtremeGrief I did it in my tool - you can disable only the M$ Defender (it's written in the description of my tool), so, M$ Defender will turn on (starts) in the next computer start.
