The undead king of operating systems refuses to die! Windows XP, released in 2001, is somehow still commanding a higher market share (0.64%) than both Windows Vista (0.07%) and Windows 8 (0.28%) combined. That iconic blue sky and green hill background is basically the digital equivalent of a retirement home resident outliving their own children. Microsoft's engineers are somewhere crying into their keyboards while legacy systems administrators are proudly wearing their "It just works" t-shirts. The zombie OS keeps shambling along, bloody but unbowed, like Randy Marsh in South Park refusing to give up a fight. No security updates? No modern browser support? XP users: "I didn't hear no bell!"
