content: AFAIK, most of the problems with Windows 10 are not the kernel. It's things like spyware and forced updates.  Unless the Windows kernel now incorporates most of the functionality on the system, it probably doesn't have a whole lot to do with it.  If anything, I get the impression that the kernel is generally one of the few things that actually consistently tends to improve between Windows versions. That said, I wouldn't be overly surprised if, at some point, the ecosystem of Windows were ported to a Linux-based kernel.  It's unlikely, but a decade ago people would probably have said the entire Windows 10 fiasco wasn't terribly likely, either.
