With this improvement, the OS can detect a higher level of SMM compliance, enabling devices to be even more hardened against SMM exploits and vulnerabilities. In this release, Windows Defender System Guard enables an even higher level of System Management Mode (SMM) Firmware Protection that goes beyond checking the OS memory and secrets to other resources like registers and IO.
