As per the link above, SMB 1 will no longer be installed by default in Win 10 1710 (which, given the release date, I’m guess that’s what it will be called) or the next version of Server 2016 (whatever that ends up being called).
Considering the recent-ish SMB1 targeted attacks, this isn’t surprising – and is a good move in my opinion. Issue is of course, the companies likely to hit by SMB1 (or other old-school attacks) are likely to not be up to date with their patching and even less likely to be up to date with OS versions – so it wont help secure the more vulnerable networks out there….
