Sets FTH\Enabled = 0. The Fault Tolerant Heap silently applies compatibility shims to apps it decides are crashing, which can slow them down and mask the real fault. Disabling keeps app memory behaviour predictable. Reboot required.
MaxTweaks applies this tweak with one click and snapshots your original setting first, so you can revert it cleanly at any time. A System Restore point is offered before batch changes, and every tweak links to its official source.
