But in general it is was harder to find information about Windows, than linux. Most of the time when it comes to a problem with Windows a solution is posted, that dosen’t explain how the solution was discovered. I found with Linux there is often more information given. And obviously with Linux you can just look at the code in the Kernel if you need to dig deep, with Windows that is not an option.
I’m not aware of any Website that goes into detail. There are however books that go into detail of how Windows works internally: https://learn.microsoft.com/en-us/sysinternals/resources/windows-internals
In general to poke around in Windows the sysinternals tools distributed by Microsoft are great. The developer of the Sysinternals tools also gave some talks going through how he uses the tools to debug problems that occurred. Those are freely available on the web.
