Microsoft’s CEO Satya Nadella announced that the number of devices running Windows 11 has exceeded one billion worldwide. He revealed the milestone during the company’s recent financial results presentation, highlighting the operating system’s broad adoption across consumer and enterprise installations.
Windows 11 reached the one-billion mark in 1,576 days after its launch. That pace outstrips its predecessor: Windows 10 needed 1,706 days to hit the same threshold. By this measure, Windows 11 has become Microsoft’s fastest-growing operating system in terms of user count.
First released in October 2021, Windows 11 will celebrate its fifth anniversary in 2026. The platform has seen steady updates since launch, and Microsoft has adjusted its development and update cadence to drive broader deployment among compatible PCs and devices.
In recent years Microsoft has placed particular emphasis on integrating artificial intelligence capabilities into the operating system, positioning AI as a central pillar of the platform’s long-term strategy. That shift reflects the company’s intent to make AI-enhanced features a core part of the user experience and ecosystem moving forward.
