Sets NoLowDiskSpaceChecks = 1 under the per-user Policies\Explorer key. Suppresses the recurring 'You're running low on disk space' balloon/notification that Windows fires for any drive under ~10% free. Useful when you intentionally keep a small drive (a fast scratch SSD, a nearly-full games drive) near capacity. The drive still works normally; you just stop being nagged. 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.
