anti-cheat update or?

ok so I know this is kinda more microsoft-related (I think anyway) but it ONLY happens when I try to launch MCC it pops up “run windows update by October and go to blah-blah for more details” but the problem is my windows IS updated, and October clearly came and went without issue. I can still play the game just fine but wondering if its something specific with Halo’s E-A-C or whatever. Also because going to microsoft support they say the page just doesn’t exist

anybody else have this happen every single time you go to launch MCC, or know if its of any real impact and probably more important how to freaking stop it from popping up?
