Why does Windows 10 disable memory integrity (HVCI) when SM14, SM14 SE or MM14 are installed?

In

If Windows 10 detects the installation of an application that is not compatible with the memory integrity feature, Windows 10 will disable the feature in order to prevent system instability. Users may notice that memory detection has been disabled Windows 10 if they install older BAPCo benchmarks such as SYSmark 2014, SYSmark 2014 SE, or MobileMark 2014.

BAPCo recommends updating to the latest generation of SYSmark 2018  and MobileMark 2018 for users who wish to test with memory integrity enabled.
