How do I learn windows inside and out?

Hi! You know, I want to learn how to completely master the latest Windows operating systems. I don't want to get certified but I do want to learn how to eventually repair and solve complex issues related to Windows. Problem is when I googled on how to go about this there wasn't a lot of information on that.
I want to give free tech support down the line. To me its more of a hobby then a career, I know it seems silly but I believe I would enjoy it so much more as a hobby then as a career.

There's also a tonne of books out there that start from "A complete idiot's dummy guide to beginning" through to graduate level texts, academic papers, technical papers etc that go into the minutiae of the most arcane parts of Windows. Find you level, and interest, and start reading.
I learned some things about windows, like kernel mode, user mode, what threads and pages are, how virtual and physical memory work together ect.
I believe I am just below a novice. Is there any books in particular order I should read? I just don't want to jump into more advanced books when I am not ready for it. Know what I mean?
There are certification guides for the Microsoft exams, but they are designed with an enterprise focus, so will likely include a lot of things which aren't relevant.
Technet is a good resource for more detailed technical documentation. It might also be of interest to you to sign up to Microsoft Developer Network, since you get access to more of the under the hood info.
Upgrading and Repairing PCs by Scott Mueller (I think 22nd edition is the current), is good for hardware.
I am keeping paid options opened. There is just so much to the Windows ios that its mind boggling. I found some book series like, windows internals, troubleshooting with the windows sysinternals tools and Windows sysinternals administrators reference.
I haven't gone through the Windows Internals book series myself but those that have really recommend it.
