apps in windows are, and have always been, more like this than mac apps. it seems like the worst offenders on mac are ports from / native residents of windows. steam does this, for example. it drives me BONKERS. at least on Mac it's kind of rare. on windows, i swear to god every single thing you install does this. razer mouse? better run at startup! weird USB peripheral you use once in a blue moon? better run at startup!
