Windows is the leading desktop operating system with more than 70% of desktops using it globally, according to StatCounter. As of January 2022, 1.4 billion monthly active devices ran Windows 10 and Windows 11, and the number of devices running Windows 11 more than doubled in 2023. In October 2025, Microsoft will end support for Windows 10, pushing millions of users to Windows 11 — an opportune moment for effective regulatory oversight.
