What happens when an AI agent encounters malicious instructions? 🛡️
With Microsoft Execution Containers (MXC) and the Microsoft Security stack, Windows enables security teams to detect risky agent behavior and restrict agent access without blocking the user.
See how Windows helps contain threats while keeping developers productive. 👇

I came home from a Microsoft dinner with a Surface Laptop Ultra in a metal briefcase. Consider me a Windows woman now.
128GB of unified memory has me curious about the future of private, local AI. Here’s the unboxing and my first look. It's going for ~$6k.

Set up OpenClaw out of the box on the new @nvidia RTX Spark laptops.
Choose a local model or connect a cloud provider, and follow the guided setup without opening a terminal.
Thanks to the NVIDIA and @Microsoft teams who worked with us on this.

An update for builders using Codex on Windows:
We’ve built a new sandbox mode using @Microsoft’s Execution Containers (MXC) for faster setup, stronger network enforcement, and granular file access controls.
Requires a compatible Windows 11 device.
Today, we announced new @Windows platform capabilities and @surface devices built to empower people and organizations for the era of hybrid intelligence. Here are some of the highlights:
- It all starts with trust. Microsoft Execution Containers (MXC) is now generally available on Windows 11, keeping agents contained within boundaries the operating system enforces.
- HydraFusion brings hybrid intelligence to life, allowing models to run locally while seamlessly accessing the cloud when more scale or capability is needed. We're working with @github to extend HydraFusion to Windows.
- This fall, Search on the taskbar adds thousands of quick actions, making it easier to adjust settings and get things done as fast as you can type.
- @MSFTCopilot is getting more powerful on Windows. With hybrid intelligence, it can tap into your PC's local capabilities and turn your requests into action, while keeping you in control.
- Local agents are coming to Windows too. Muse is on its way as a native Windows app with MXC integration, and Hermes, OpenClaw, and Perplexity are already building local experiences on Windows.
- Surface Laptop Ultra, built with NVIDIA RTX Spark, is the most powerful Surface we've ever built. It's available for pre-order today, along with the Surface RTX Spark Dev Box and new RTX Spark PCs from our partners. Call of Duty is coming to RTX Spark in 2027.

Excited to announce the Replit desktop app preview with @Microsoft (@msdev).
On @Windows, Replit builds and runs apps locally, and each build runs in its own sandbox powered by Microsoft Execution Containers and @Nvidia OpenShell.
