Sets ShowTaskViewButton = 0 under Explorer\Advanced. Removes the Task View icon from the taskbar. Win+Tab and virtual desktops still work via the keyboard — this just reclaims the taskbar slot and removes a button most people never click. Takes effect immediately 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.
