Since 1985, that is the first version of Windows, the Notepad has served all sorts of users for taking notes and obviously even coding. However, never has it played well with other types of line feeds, including the ones Linux text editors use.
This means that in the worst case you'll just have one endless line, and everyone knows, or can imagine, how frustrating that is to edit.
While this seems like a minor problem, as the Microsoft presenter below notes (no pun intended), it's often the little things that matter the most. And thus, after decades of frustration from developers, Microsoft has fixed the Notepad and it finally supports Linux line feed.
You'll find the new, fixed and improved, Notepad in the upcoming updates of Windows 10.
