Sets EnableClipboardHistory = 1 so Windows keeps a multi-item clipboard you can open with Win+V and paste from. A big productivity win that's off by default. 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.
