That "pinned-and-running-programs-shown-together-with-just-an-underline-to-distinguish-running" is one of the numerous UI regressions introduced with Windows 10. I can only suppose that at the time of XP development, Microsoft used to respect quality UI designers who emphasized usability first, and when Windows 8&10 appeared, MS was just trying desperately and wrongly to look cool and tabletish because of Android's rise. It was a major disaster, a big step back in the Windows user experience. Other basic things like sensible highlighting, coherent visuals for overlapping windows, window edges, scrollbars, UI tuning etc. went "out the Windows 10".
Solution: I restored the Quick Launch toolbar as soon as I upgraded to Win10, and decided to never pin anything to the taskbar; never have since then. Clear separation of taskbar items: launch buttons on the left, running programs center, and background system/utility programs on the right (tray). Also less clutter and better visibility with WinaeroTweaker and "Classic Start Menu".
