The past decade has been about moving to the cloud, more than anything else, and this is a space where the OS mostly receded into the background. However, Linux, with its namespaces, provided LXC and subsequent innovations that leveraged namespaces to usher in the container revolution. I think this has safely put Linux in a league of its own. eBPF may cement Linux's status as the OS of the cloud if it is adopted widely. So there's a lot of action in things that build on OS innovations, but OS innovations themselves have been much slower I think. And the Microsoft with its 'openness' winning over Apple is a story that ignores the phenomenon that is the mobile phone completely. It's iOS and Android, not Microsoft Windows that's the definite winner in that space. Microsoft has a much more mature and well-loved tech stack that was the de-facto choice of developers in the 90s and aughts but failed to capitalize on that in the mobile world.
