As a new user, can't create a new thread? Anyway, does anyone have the DirectX 12 runtime provided with the latest update of World of Warcraft? I don't have WoW... just curious if it is a game specific solution or a system wide one.
Yes if you want to continue to receive updates, as MS will not be supporting updates with SHA-1 in few months time.
Yes, absolutely. Without full SHA2 codesigning support, you won't get further updates (as the signature checks will fail).
