OK, then you are an exception because most conversations regarding this are almost never based on that. When is the last time someone bought a kernel for their computer? Or asked what kernel version is on your phone?
I hate to break it to you - well actually I don’t but anyway - you’re beloved windows actually has a kernel too.

So far your knowledge of OS seems to be Windows logo - good, Kernel - bad, but it turns out that even that limited definition is inherently contradictory. LOL.
