Microsoft is bringing Meta’s AI agent to its home turf. At the company’s Windows and Surface event in San Francisco on Wednesday, Microsoft announced that Muse, Meta’s personal AI agent, is coming to Windows as a native app.

Windows and Surface chief Pavan Davuluri made the announcement on stage, according to Windows Report, which covered the event live. Microsoft did not share a release date, saying only that the app is coming soon.

The Windows app closes the last gap in Muse’s desktop coverage. Meta launched the agent on September 8 for iPhone, Android, and the web, shipped a Mac app in mid-September, and added a native iPad app on Wednesday morning. A Windows version puts Muse on the world’s most-used desktop operating system and places Meta’s agent directly alongside Microsoft’s own Copilot.

Built on Microsoft’s agent security model

The Windows app will ship with integration for MXC — Microsoft Execution Containers, Microsoft’s framework for running AI agents safely on Windows, which became generally available on Windows 11 the same day as the event.

MXC lets organizations define which files and networks an agent can reach, with policies enforced at runtime and kept outside the agent’s own control, so a workload cannot grant itself additional access. Microsoft pairs that containment with identity (so IT departments can tell which agent performed a given action) and manageability through Agent 365 and Intune. On Windows, MXC can run an agent in a separate OS-isolated session with its own identity, clipboard, and desktop.

Muse joins a growing list of agents supporting MXC, which already includes OpenAI’s Codex, GitHub Copilot, Replit, and LM Studio, with Anthropic’s Claude Code, Manus, and Perplexity among those planning support, according to Unite.AI’s reporting from the event.

Muse has faced security and privacy questions since launch, most recently the pre-launch scramble 404 Media reported, in which Meta rushed to patch virtual-machine escape flaws weeks before release, and Apple’s macOS privacy changes after Muse was found reading users’ message data. Running inside Microsoft’s containment model gives enterprise IT the controls needed before letting an agent loose on company machines.

Why it matters

The announcement is a rare moment of cooperation between Meta and Microsoft, which is otherwise racing it on AI agents. Microsoft has been pushing Windows toward an ecosystem where different agents work alongside Copilot, and a native Muse app puts Copilot, Muse, Codex, and Claude Code on the same desktop, competing for the same users.

Windows users, who currently reach Muse only through the browser at muse.ai, will get a native app with the kind of OS-level access the Mac app already has: files, messages, calendar, and mail, with the user’s permission.

Meta has not yet confirmed the announcement on its own channels. MobileSyrup’s event coverage independently confirmed the announcement. As Windows Report noted, more details should emerge closer to launch.
