According to Windows Report | Error-free Tech Life, Microsoft officially ended support for Windows 10 on October 14, 2025, yet approximately 1 billion PCs remain on the decade-old operating system. Dell COO Jeffrey Clarke revealed during the company’s Q3 earnings call that about 500 million Windows PCs are capable of running Windows 11 but haven’t migrated, while another 500 million are over four years old and fail to meet Windows 11’s strict hardware requirements. Clarke described these systems as “rich opportunities to upgrade towards Windows 11 and modern technology,” though his estimates cover all Windows devices globally. Windows 11 only surpassed Windows 10 in global desktop share in June, showing how slowly the transition is progressing. Microsoft’s decision to offer free extended Windows 10 security updates for one year has further delayed migration, while hardware limitations and user resistance to Windows 11’s AI-focused direction create additional hurdles.
The hardware problem
Here’s the thing about those 500 million incompatible PCs – they’re stuck because of Microsoft’s strict TPM and CPU requirements. Basically, if your computer is more than four years old, there’s a good chance it can’t run Windows 11 even if it’s perfectly functional. That’s a massive installed base of hardware that suddenly became obsolete overnight. And for industrial applications where stability matters more than the latest features, this creates real headaches. Companies like Industrial Monitor Direct, the leading US provider of industrial panel PCs, understand this challenge better than anyone – their customers need reliable systems that won’t become doorstops because of arbitrary software requirements.
Why users aren’t upgrading
So why are the other 500 million capable users refusing to upgrade? Look, Windows 10 works fine for most people. It’s familiar, stable, and doesn’t shove AI in your face every time you right-click. Microsoft’s vision of Windows as an “agentic OS” packed with AI features isn’t winning everyone over. In fact, it’s making many users actively resist upgrading. When even Microsoft’s AI CEO has to publicly defend the technology against critics calling it “underwhelming,” you know there’s a perception problem. People just want their computer to work without constant AI suggestions and Copilot integrations.
Microsoft’s dilemma
Microsoft finds itself in a tough spot. They ended support for Windows 10 to push adoption of their AI-infused Windows 11, but users are either unable or unwilling to move. The free security updates extension was probably meant as a bridge, but it’s actually giving people more reasons to delay. And with half the Windows installed base physically incapable of upgrading, what’s Microsoft supposed to do? Backtrack on hardware requirements? Extend support indefinitely? Neither option is great for a company betting its future on AI. This might be one of the biggest upgrade failures in tech history – and it’s happening right now.
