What you'll find will happen, that unbeknown to you, or possibly even known, at some stage you'll accept updates for "other good things from Windows/Microsoft" (my wording!!). This switches updates back to fully automatic. Very annoying I'll agree. The only honest answer is to get into Windows updates and re-set (in my case to never. I'm big enough, old enough and ugly enough to get my own update regime, thank you very much!) to your personal method asap. Installing office does exactly the same. I think with Live its part of the I agree terms that you agree to.
