Hi, happy to be part of this forum, I am new and beginner. :D
I am learning more and more to understand how the OS and Kernel work and I ask to learn about the Windows 7 x86 version, was appropriate?
I would have no trouble adapting to version 10 of Windows, or is it really different?

Hi Bob,

I think the Windows 7 - to Windows 10 step would not be a big deal if you really started to understand the inner working of the windows 7 kernel.
But why would you choose to learn about the windows 7 kernel if you could directly dig into windows 10?

Since you stated you are a beginner, I'll give you some hints to get started.
Windows Internals (Book covering pretty much exactly what you seem to want to learn)

Also covering the Windows kernel:
Practical Reverse Engineering: x86, x64, ARM, Windows Kernel, Reversing Tools, and Obfuscation (ISBN: 978-1-118-78731-1)
Also covering windows and a lot more reversing
Reversing: Secrets of Reverse Engineering (ISBN: 978-0764574818)

My personal favorite is the first book. Just have a good read on the parts you are interested in and read something about general reversing in all of this books.

Enjoy!
