Based on https://stackoverflow.com/questions/5020418/how-do-i-turn-off-the-fault-tolerant-heap it seems like there’ll be an entry in the registry for your application, such as HKLM\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers\your_application.exe or HKCU\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Layers\your_application.exe that you can query.
