Re: Am I confused, or is the author?
The Windows Runtime, despite the name, isn't really a "runtime" in the sense of something like the .net CLR or Java JVM, i.e., it's not a kind of VM running intermediate bytecode. It's just a set of APIs exposed by Windows that use newer patterns designed to be used by multiple languages, including C++ apps which are compiled to native machine code like any C++ program, whether they're using WinRT APIs or not.
