Control Flow Guard (CFG) is an exploit mitigation feature that Microsoft introduced in Windows 10 and Windows 8.1 Update 3 that makes it significantly harder for exploits to run code on systems running these operating systems. This year’s major Windows 10 update (called the Anniversary Update) introduced improvements to CFG. The Anniversary Update began its rollout to most users in August 2016, although it may not be finished deploying to all users until this coming November.
