Microsoft is issuing warnings to its global user base of 1.4 billion as the October 14 end-of-support date for Windows 10 approaches, a deadline affecting over 500 million users who must either upgrade or pay for extended security updates.
Data from StatCounter, which analyzes device-based signals to determine operating system distribution, indicates that 630 million individuals, or 45% of the user base, are currently using Windows 11. The same data shows 490 million people, representing 35% of users, remain on Windows 10. A more unexpected finding from the data suggests that approximately 300 million users, or 20% of the total, have installed Windows 7. This operating system officially retired in 2020, and its use presents a significant security vulnerability for those machines.
This reported resurgence in Windows 7 usage has been noted by industry publications. According to Windows Central, “Windows 7 usage seemingly skyrockets as users refuse to upgrade to Windows 11 in wake of Windows 10 end of support.” The publication acknowledges, however, that the “sudden marketshare gain is likely a data anomaly, but interesting timing nonetheless.” The revival of an unsupported OS at this scale is considered highly improbable by technology analysts.
Countering the report of a surge, Windows Latest states, “no, Windows 7 isn’t gaining market share in 2025.” The outlet questions the practical feasibility of such a trend, posing questions about the availability of Windows 7 ISO files and the functionality of an outdated system. It highlights that most new games, drivers, and applications lack compatibility with the decade-old OS. As an example, the publication noted an inability to install even Windows 10 on a Spectre laptop because its drivers were strictly locked to Windows 11, illustrating the challenge of installing an even older OS on modern hardware.
Microsoft has officially cautioned against using unsupported software. The company states that “an unsupported version of Windows doesn’t receive software updates. These include security updates that protect your PC from harmful viruses, spyware, and other malicious software, which can steal your personal information.” This lack of protection is the primary reason users are advised to migrate from retired systems. The same logic applies to Windows 10, which will cease receiving these critical security updates after its official end-of-life date.
