The OS has half the desktop market share in August. The Tame Apple Press has mocked the achievement saying that Vole originally aimed to hit one billion devices running Windows 10 "in two to three years".
A year in, the company backpedalled on that goal after becoming clear that Windows 10 Mobile was a failure. (Android has over 2.5 billion monthly active devices.)
Windows 10 was released four years and eight months ago in July 2015. It thus took the company more than double its ambitious estimate and 20 months longer than its conservative estimate to pass one billion Windows 10 devices.
Microsoft also said that Windows 10 powers 80,000 models and configurations of laptops and 2-in-1s from over 1,000 different manufacturers. HoloLens, today's Xbox consoles, and the upcoming Xbox Series X all run Windows 10 variants.
A spokesVole said: "One in every seven people on the planet are planning, creating, ideating, executing, moving, shaking, and doing great things with Windows 10. With 100% of the Fortune 500 now using Windows 10 devices, it has become a critical platform for driving business transformation in the enterprise and beyond. As companies transition from Windows 7 to Windows 10, they are committing to running their business more efficiently, more securely, and positioning themselves to offer better products, services, and solutions to their customers."
