If you're looking to learn about WHY the code works, then you need to go into a much deeper dive into the inner workings of the OS and computer architectures. On windows, you're best bet is that you'll learn by something telling you how/why it works, unless you work at MS, then you'll -know- how/why it works. For Linux, there is stuff like LFS, which you'll be able to learn and know how/why your OS works.
Will learning that make you a better developer? Maybe. It all depends on what you're doing. Almost all of that is too much info for a business app developer. But if you're doing interesting things with your computer, or chasing some really nasty bug, then that info can become invaluable and a huge time saver.
Will your IDE guide you in any of that? Nope, its not its job.
