You know one thing I really hate about Windows?
When you’re doing a giant file copy, and there are several files mixed in that have attributes that set off the “are you sure you want to copy this?” pop-up. And you hit “Yes to all” that first time, assuming it will be the only time you have to hit a button. But lo, and behold my children, for that “yes to all” apparently only applies to the current folder you are copying, or something (I never bothered to figure out the specifics) not the entire file copy, like it should. So you wind up hitting “yes to all” once for every sub-directory (or whatever) that contains a trigger file.
That really annoys me.
