Fair enough, and I appreciate the clarification. That actually reinforces my point. You and I both work with people who use Windows daily and encounter these verbose errors—but they almost never understand them. They don’t use these messages to develop troubleshooting skills—they just get stuck and frustrated.
So while I get the appeal of a detailed error message in theory, in practice, it doesn’t help most users learn anything. If anything, it just creates more dependency on people like us to fix things for them.
