Sets TaskbarGlomLevel = 2 under Explorer\Advanced. Stops Windows from stacking multiple windows of the same app into one taskbar button — each window gets its own labelled button, so you can click straight to the exact window instead of hovering to pick from a stack. A long-requested productivity win, especially with many documents/browser windows open. Takes effect on the next Explorer refresh. 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.
