Sets HistoricalCaptureEnabled = 0, turning off the Game Bar's 'record the last X minutes' background ring buffer. That buffer continuously re-encodes gameplay in the background, spending GPU encoder time and RAM even when you never save a clip. Disabling reclaims both. Safe and reversible.
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.
