Microsoft ended free security support for Windows 10 this week, though millions of people still use personal computers running the older operating system.

To entice people to upgrade, the software giant on Thursday announced new Windows 11 features, most of them further integrating the company’s AI chatbot, Copilot, into the experience of using a laptop.

Among the features is a voice mode that enables users to dictate “Hey, Copilot” to start chatting with their computer instead of typing or clicking a touchpad.

Microsoft first introduced Windows 10 a decade ago and launched its successor, Windows 11, in 2021.

But many people around the world still are using Windows 10, particularly those with older computers that can’t upgrade to Windows 11. Consumer advocates have spent months petitioning Microsoft to extend technical support for an estimated hundreds of millions of devices that will no longer get automatic security fixes.

“With the end of Windows 10, users face the choice between exposing themselves to cyberattacks or discarding their old computers and buying new ones,” said Brenna Stevens of the Oregon State Public Interest Research Group, which advocated on behalf of local repair shops, students and others.

Microsoft has said people can pay extra for a year of extended security support through October 2026. Some users, including those in the European Union as well as U.S. users who can synchronize with Microsoft’s cloud service, will be able to get that extended support for free.

But most people faced with unsupported devices are likely to either keep using them despite the vulnerabilities or throw them away, which “creates both a security problem and an environmental problem,” generating huge amounts of toxic electronic waste, said Nathan Proctor, who leads PIRG’s Right to Repair campaign. Both PIRG and Microsoft urge those who are replacing their computers to avoid sending their older models to the landfill.

Those concerns were not a focus of Microsoft’s Windows 11 announcements Thursday. Instead, Yusuf Mehdi, an executive vice president and chief marketing officer for Microsoft’s consumer division, argued that conversing with a laptop will be “as transformative as the mouse and keyboard” in shaping the PC experience. Microsoft says all Windows 11 users will also now have access to Copilot Vision, an AI feature that can analyze and give feedback on the documents, video games and other activities happening on the screen.

Mehdi acknowledged it could take some adjustment to get used to human-computer conversations in shared workspaces.

“Just like when the mouse came out, people have to figure out when to use it, what’s the right way, how to make it happen,” Mehdi told reporters.

The updates are Microsoft’s latest attempt to make its widely used Windows operating system a gateway to hook people on its suite of generative AI tools. The tech giant competes heavily on AI services with Apple, Google and startups like Anthropic and OpenAI.

Mehdi said the updates are “not a replacement for Recall,” a screen-tracking feature on some Windows computers that gives Copilot a “photographic memory” of a user’s virtual activity. Microsoft CEO Satya Nadella described it last year as a step toward machines that “instantly see us, hear, reason about our intent and our surroundings,” but the idea was met with criticism from privacy and security experts and took a year before it started to roll out.
