Microsoft allegedly plans to bring Copilot, its generative-AI-powered personal assistant, to late adopters. Windows Central’s Zac Bowden reports the Copilot button and sidebar from Windows 11 will “soon” arrive in Windows 10. The AI assistant for Windows 11 launched in beta in August and officially in September.

Bowden says the Windows 10 Copilot will include plugins that work across both operating systems. “I understand the experience and capabilities of Copilot across Windows 10 and Windows 11 will be roughly the same, including plugin compatibility across both versions of the OS,” the editor reported.

The move would add significant numbers to Copilot’s user base, as Windows 10 still runs on around one billion monthly active devices. Meanwhile, Windows 11, launched over two years ago, has around 400 million monthly active devices. Bowden suspects the move will also help Microsoft nudge developers into making Copilot plugins: “Microsoft will also have an easier time selling developers on the idea that they should build plugins for Copilot when they can say Copilot is available on 1.4 billion devices, compared to just 400 million on Windows 11.”

Engadget contacted Microsoft for comment but didn’t immediately receive a response. We’ll update this article if we hear back.

Bowden’s report also mentions that Microsoft is revisiting its strategy of moving on quickly from Windows 10. The company reportedly plans to add “select new features and services” previously exclusive to Windows 11 to the older OS. Windows 10 support is set to expire in October 2025, but Bowden’s sources say the company is having ongoing internal discussions about possibly extending that.
