Yes, the story is not that notepad is in some weird place in windows 10 - it is still where most HN readers know to find it.
The story is about how regular people deal with computers, as can be read in the comments.
It's like that story about how one day the google search 'facebook login' took people to a forum page that let people comment using their facebook credentials, and we got to find out how many users just type 'facebook login' to whatever text field they run across, type their username and password in, and then get really confused when it's a random forum page and they can't see their normal feed.
