windows vista
If cars ran on Windows Vista:

7:30 am. Johnny goes to get in his car (that he's making $700 monthly payments on). As soon as he turns the key, the car freezes. He tries to shift the car into reverse, but it doesn't respond. He fiddles with it for a couple minutes, before the car starts. He has to go through a range of windows to give permission for it to work. "Gearshift.exe needs your permission to run." "Steeringwheel.exe", "Radio.exe", etc. By the time he leaves, it's 7:37 and he's probably going to be late for work.

He's on a country road fifteen minutes later, when he gets a message. "Steeringwheel.exe has stopped working, Windows is checking for a solution." just as he's about to go around a curve. Just as he slams head on into a Windows 7 car, his car says "Airbag.exe needs your permission to run." Obviously he can't react in time for the crash, so the airbag doesn't deploy. After the crash, his hand slips, hits "Yes", and the airbag punches him in the face, causing further injury. The driver of the Windows 7 car walks away.

Good thing the emergency room doesn't run on Windows Vista.
Windows Vista is better than Windows ME, and worse than Windows 3.1, 95, 98, 2000, XP, 7, 8... well pretty much any non ME Windows released since 1990.
