This is a dishonest article with a misleading, attention-grabbing, clickbait-worthy headline, and is no different to other reporting recently (e.g. Stallman) where quotes are taken out of context and misrepresented into something completely different to fit the writer's narrative.
I'm 100% sure that if you asked the Microsoft CEO if Windows is important, he will confirm that it is in fact important to Microsoft. The headline "Microsoft doesn’t think Windows is important anymore" is extrapolated from a quote of Nadella's where he is discussing the new Neo and Duo devices. Read in the original context you can see that at no point does he say that Windows is not important to Microsoft, he is just giving some justification for not wanting to revive the Windows Mobile OS.
