Microsoft today claimed that Windows 10 powered a billion devices, a milestone the company originally said it would meet between one and a half and two and a half years ago."Over one billion people have chosen Windows 10 across 200 countries resulting in more than one billion active Windows 10 devices," asserted Yusuf Mehdi, corporate vice president, in a March 16 post to a company blog.The bulk of those devices were undoubtedly desktop and notebook PCs, although Microsoft also tallied Xbox game consoles, which run a version of Windows 10, as well as extremely niche devices, like the Surface Hub.
