Earlier this year, Microsoft ended support for Windows 10, urging users to switch to Windows 11. Despite this, 500 million PCs capable of running the new OS—out of roughly 1.5 billion worldwide—have not upgraded.

User Concerns and Resistance

Many users cite frustration with Windows 11's unfamiliar interface and the presence of AI features like Copilot as reasons to remain on Windows 10. Microsoft's Windows president, Pavan Davuluri, referred to the new OS as an “agentic OS,” which faced user backlash. Critical user comments suggest resistance to this direction, with some considering alternative platforms like Mac and Linux.

Industry and Developer Reactions

Dell's COO Jeff Clarke noted that half a billion Windows PCs are not eligible for the upgrade. Developers like Gergely Orosz express confusion with the AI-driven path, affecting the decision to develop for Windows. Microsoft executive Yusuf Mehdi mentioned plans to integrate AI deeply into the operating system, transforming PCs into AI-driven machines. This has prompted concerns over the system's orientation away from traditional computing values.

Security and Environmental Implications

Analysts warn that the large base of unsupported Windows 10 machines could pose a security risk as updates cease. An advocacy group estimated this shift could create 1.6 billion pounds of e-waste. Microsoft is attempting to address usability for power users, hoping to assuage concerns and prompt more upgrades. Whether these efforts will succeed remains uncertain.
