I'm one of these customers who spent a lot of time researching this, checking our systems, traffic, investigating what older systems might be affected by this, nagging our partners for answers, preparing group policies to push needed updates and registry changes on 10.31. Although back in my mind i was expecting it to be postponed again. There are just too many old systems in the world. And i'm not sure when TLS 1.2 would be safe to be enforced, probably when 1.8 is released and 1.2 would be deprecated :D Seriously though, it feels like an unwinnable battle. MS tries to stay as safe as possible and can't, because customers won't/can't update (although in this case it seems they can't even update their own software). I have experience in software development and i know how users tend to stick to older versions because they are used to it, don't want to change settings, etc. Often for them it is better than stay secure. Well, will see what the next date will be.
