As the calendar turns to October, a notable trend emerges in the world of operating systems. Windows 10 appears poised to experience a decline in its user base, primarily driven by the rising costs associated with Extended Security Updates (ESUs). The financial implications are significant, with the total cost for three years of ESUs reaching approximately 7 per device. This increase in expenses may prompt many users to reconsider their allegiance to Windows 10.
Historically, the transition from older operating systems has shown a pattern of accelerated user loss after the third year of support ends. A case in point is Windows 7, which witnessed a substantial drop in its user base following the conclusion of its support period. Such trends suggest that Windows 10 may face a similar fate as users weigh the costs against the benefits of remaining on an outdated platform.
Windows 11’s Ascendancy
In contrast, the latest data from Statcounter indicates a robust growth trajectory for Windows 11. As of September 2026, this modern operating system commands an impressive 71.5% of all Windows installations. This surge in market share follows a relatively stagnant year for Windows 11, marking a significant turnaround as users increasingly embrace Microsoft’s latest offering.
The uptick in Windows 11 adoption can be attributed to the official end of support for Windows 10 in October 2025, which has undoubtedly catalyzed a wave of migrations to the newer platform. As businesses and individual users alike seek to stay current with technology, the allure of Windows 11’s enhanced features and security measures becomes increasingly appealing.
In this dynamic landscape, the interplay between operating system support, user costs, and market trends continues to shape the choices of millions. As Windows 10 users contemplate their next steps, the momentum behind Windows 11 suggests a bright future for Microsoft’s latest endeavor.
