Microsoft is urging users to transition from Windows 10 to Windows 11 due to the approaching end of support for Windows 10 on October 14, 2025. In June, Microsoft issued a full-screen notification warning users about the lack of technical support and security updates after this date. As of July 2024, Windows 11 has surpassed 30% market share for the first time since its launch in October 2021, with over 7% year-over-year growth. However, more than twice as many users still rely on Windows 10 compared to those who have switched to Windows 11. The transition is expected to accelerate as the October 2025 deadline approaches, but many users may risk operating without official support, increasing their vulnerability to cybercriminals.
