Microsoft Execution Containers (MXC) is a policy-driven way to run AI agents and the code they generate inside an independently enforced boundary. You declare which files, processes, network destinations, credentials, and user-interface resources an agent may use. MXC then maps that policy to a suitable containment technology, from a lightweight process boundary to an experimental hardware-isolated microVM. If the agent or generated code requests an operation outside the policy, the boundary is designed to block it rather than trusting the model to make the safe choice.
For Windows developers, that means you can start with a narrow policy, observe what a coding agent actually attempts, grant only the required resources, and move to strict enforcement for production. The right option depends on whether you need low latency, a separate desktop session, Linux compatibility, or stronger hardware-backed isolation.

What is Microsoft Execution Containers, and why does it matter?
Microsoft Execution Containers (MXC) is an execution layer for untrusted code and dynamically generated workloads. It can contain a model-generated script, a plugin, a tool, an agent harness, or the complete agent process. The developer or organization defines the security policy; the workload runs inside a boundary that is enforced outside the model.
That separation is the central idea. An agent may be instructed to edit one repository, call a small set of APIs, or run a test suite, but its instructions and generated code are not a security authority. If it tries to read a private directory, open an unapproved network connection, or start a disallowed process, MXC evaluates the request against the declared policy. The containment layer, rather than the agent, decides whether the operation proceeds.

Logan Iyer, Microsoft’s Corporate Vice President for Windows Platform + Developer, expressed the principle on October 7, 2026: “An agent cannot be its own security authority. It must run within a boundary defined by the developer or organization and enforced independently of the agent itself.” Microsoft described MXC as generally available in that announcement, while some integrations and management features remain forthcoming or experimental.
MXC is therefore a runtime control, not a complete security program. It reduces the damage an agent can cause within the covered boundary, but it does not replace endpoint protection, identity governance, code review, or careful least-privilege design.

How does MXC enforce an AI agent policy?
A policy is multidimensional. Instead of granting an agent a vague “sandbox,” you describe the operations and resources required for a particular job.
- Containment type: Choose the process, session, WSL, or microVM boundary appropriate to the workload.
- Process command and environment: Specify what command starts the workload and which environment variables it receives.
- File-system access: Define paths that may be read, paths that may be written, and paths that must be denied.
- Network access: List permitted outbound destinations and any inbound listeners. Treat loopback behavior as a separate decision because local services can expose sensitive interfaces.
- User-interface access: Decide whether the workload can interact with a desktop, clipboard, keyboard, pointer, or other UI input.
- Credentials: Inject only the credentials needed for the task and scope them to the smallest possible permission set.
These controls apply to the covered command and its child processes. A policy cannot protect a process, credential, or resource that you deliberately leave outside the boundary. Broad network access, an unsandboxed fallback, or a secret injected with excessive rights can still undermine the effective isolation.
Which MXC containment option should you use?
Use a process container for responsive command-line work, a session container when an agent needs its own Windows desktop, a WSL container for Linux-first tooling, and a microVM when the workload warrants a stronger hardware-enforced boundary. The microVM option is experimental, so validate it before relying on it for production workloads.

| Option | Best fit | Boundary and notable trade-off |
|---|---|---|
| Process container | Interactive coding agents and tool execution where startup latency matters | Lightweight process-level controls for files and network using platform primitives. It is efficient, but its protection applies to the covered command and descendants rather than an entire virtual machine. |
| Session container (Windows 11) | Long-running automation that needs a Windows desktop | Places the agent in a separate Windows account and session, including a distinct desktop, clipboard, UI, and input context. It is appropriate when graphical interaction is part of the job. |
| WSL container (Windows 11) | Linux-first agent toolchains running on a Windows host | Provides a Linux environment through Windows Subsystem for Linux. Check that every required tool and file path behaves correctly across the Windows and Linux boundary. |
| MicroVM (Windows 11 and Linux, experimental) | Higher-risk workloads needing stronger isolation and full Linux compatibility | Uses a hardware-enforced virtualized boundary and supports a full Linux workload. Its experimental status means feature coverage and operational behavior should be verified for your deployment. |
Compare candidates on more than startup speed. Ask whether the agent needs a desktop, whether its toolchain is Linux-specific, how much file and network policy it requires, where credentials will live, what activity you need to audit, and how the organization will manage the host. A process container is often the practical default for a command-line coding agent; moving to a session container, WSL, or microVM should be driven by a concrete requirement rather than by the label alone.
How do you choose a boundary for a Windows coding agent?
Start with the smallest environment that can complete the task, then increase isolation when the task’s interface or risk demands it.
- Command-line repository work: Use a process container when the agent only needs a checked-out directory, a compiler or interpreter, and a short list of package or source-control endpoints.
- Graphical testing or desktop automation: Use a Windows 11 session container so the agent’s desktop, clipboard, UI, and input are separate from the operator’s session.
- Linux-native build systems: Use a WSL container on Windows 11 when the agent depends on Linux packages, shell behavior, or tooling that is not available natively on Windows.
- Untrusted or high-impact code: Evaluate the experimental microVM when a hardware-backed virtualized boundary and a full Linux environment are more important than the additional operational complexity.
Do not select a stronger boundary as a substitute for a precise policy. A microVM with unrestricted network access and long-lived administrator credentials can still expose valuable systems. Conversely, a narrowly scoped process policy may be sufficient for a disposable build task.
How do you author and roll out an MXC policy?
Policy authoring is intended to be iterative. Begin with known requirements, observe real attempts, and only then switch to strict production enforcement.
- Inventory the task: Record the command that starts the agent, its child tools, required environment variables, repository paths, package registries, source-control hosts, test services, and any UI interaction.
- Declare narrow permissions: Grant read access only to the source files the agent needs, write access only to its working and output directories, and explicit network destinations rather than an unrestricted connection.
- Choose an observation mode: Use Permissive mode to allow operations while recording would-be denials, or Learning mode to block ungranted operations and record the denied attempts.
- Review the activity report: Separate legitimate requirements from unexpected behavior. A package manager may need an additional registry, while an unrelated attempt to read a user profile should normally remain denied.
- Refine the policy: Add only the resources that the task genuinely requires. Keep sensitive paths, administrative operations, and unnecessary network destinations denied.
- Switch to Enforcement: In Enforcement mode, ungranted operations are blocked and the run proceeds without an activity report. Use this mode for production after the policy has been validated.
- Handle denials visibly: The agent or its wrapper should tell the operator which organizational policy blocked a required resource. A silent failure makes troubleshooting and approval decisions harder.
What is the difference between Permissive, Learning, and Enforcement?
Permissive records operations that would have been denied while allowing them, subject to other operating-system or organizational restrictions. It is useful for discovering the workload’s behavior, but it can expose resources during observation.

Learning blocks operations that are not granted and records those denials. It gives you evidence about missing permissions without allowing the workload to continue through every attempted path.
Enforcement blocks ungranted operations and runs without an activity report. It is the production posture once the required accesses are known.
What should a practical policy include?
A useful policy describes both what the agent may do and what it must never do. The following checklist catches common omissions before deployment.
- Working directory: Mount or expose the repository and build output explicitly. Make generated artifacts writable without making the entire home directory writable.
- Read-only inputs: Keep source, configuration templates, and reference data read-only when the agent does not need to modify them.
- Denied paths: Explicitly deny credential stores, personal files, system configuration, and unrelated repositories rather than relying on the agent to ignore them.
- Process set: Permit the agent, compiler, test runner, and required helper tools. Review scripts that can spawn shells or download and execute additional binaries.
- Environment: Pass only variables needed for the job. Avoid inheriting a developer’s complete environment, especially variables containing tokens or cloud credentials.
- Outbound network: Allow named package registries, source-control endpoints, model services, or test APIs. Decide whether DNS, redirects, and dynamically discovered hosts fit the policy.
- Inbound and loopback: Permit listeners only when a test or development server requires them. Restrict loopback connections so a process cannot reach unrelated host services.
- UI and clipboard: Keep UI access disabled for headless coding jobs. If a desktop task needs it, use a separate session and treat clipboard transfer as an explicit data path.
- Credential lifetime: Inject short-lived, task-specific credentials and revoke them when the run ends. MXC cannot make an overprivileged credential safe merely by placing the process in a container.
How can you sandbox an AI coding agent on Windows?
The exact command or configuration surface depends on the agent and the MXC integration, but the operational sequence is consistent.

- Choose a process container for a headless agent, a Windows 11 session container for desktop automation, or a WSL container for a Linux-first toolchain. Consider the experimental microVM only after confirming that its current feature set supports the workload.
- Define the startup command, child-process allowance, environment variables, read and write paths, denied paths, network destinations, loopback behavior, and UI permissions.
- Run the workload in Permissive or Learning mode. Capture every attempted file, process, network, and UI operation and inspect the activity report where the selected mode provides one.
- Remove permissions that were not required, then rerun the complete task, including error paths and tests that exercise network and filesystem behavior.
- Move the approved policy to Enforcement mode and keep the workspace disposable where possible.
- Monitor failures after deployment. When a dependency legitimately changes, update the policy through organizational review instead of granting a blanket exception.
This workflow also applies when MXC contains only generated code or a tool rather than the whole agent. Wrapping the entire agent gives a broader, simpler boundary; wrapping a risky tool can reduce overhead when the rest of the agent already runs in a trusted service.

How does MXC fit into Microsoft’s wider control plane?
Microsoft describes MXC as part of a broader Windows control plane rather than an isolated sandbox API. The company identifies connections with Entra identity, Intune policy, Agent 365 governance, Defender, and Purview. Those systems can provide organizational identity, device and configuration controls, governance, threat detection, and data-policy context around the runtime boundary.
Windows 365 support is described for deploying agents on Cloud PCs with the same containment model. That can separate agent workloads from a developer’s physical workstation, but the Cloud PC’s identity, network routes, data stores, and administrative policies still need independent review.
Microsoft names GitHub Copilot, OpenAI Codex, OpenClaw, Replit, LM Studio, NVIDIA OpenShell, and Unsloth AI among agents or tools supporting MXC. Integration availability can differ by product, channel, and release date; verify the current documentation for the specific agent before designing a production workflow. Microsoft also describes some management capabilities and integrations as forthcoming, so do not assume that every control-plane connection is available in every tenant.

Most isolation failures are scope or policy mistakes, not a missing “strongest” container. Treat the following as design checks.
| Symptom | Likely cause | Corrective action |
|---|---|---|
| The agent cannot install a required package | The package registry or download host is outside the network policy | Identify the exact destination, assess whether it is trustworthy, and grant only that endpoint or use a preloaded dependency. |
| A build works locally but fails in the container | An implicit file, environment variable, executable, or service was available on the developer’s machine but not declared | Use Learning mode to identify the missing access, then add the smallest legitimate permission. |
| A test server cannot be reached | Inbound or loopback behavior was not granted, or the server is outside the selected session | Decide whether the test needs a listener, restrict it to the required interface, and avoid exposing unrelated host services. |
| A secret is exposed despite containment | A credential was explicitly injected with broad rights or copied through an allowed channel | Use task-specific, short-lived credentials and restrict their scopes independently of MXC. |
| The agent bypasses the intended boundary | A fallback command, helper process, or external service runs outside the covered process tree | Ensure every execution path is covered, remove unsandboxed fallbacks, and review child-process and service-launch permissions. |
| Desktop automation affects the operator’s session | The workload was not placed in a separate session container | Use a Windows 11 session container for isolated desktop, clipboard, UI, and input state. |
MXC also has ordinary platform limits. Process-level isolation covers the specified command and child processes, not arbitrary programs launched elsewhere. An unrestricted network allowance can let a contained process influence external systems. Organizational policy, operating-system restrictions, and endpoint security can further restrict a run, while MXC itself does not perform code review or decide whether generated code is correct.

What should an organization verify before production?
- Document the agent, tools, child processes, repositories, data classifications, and required destinations.
- Choose a containment type based on interface and risk, not marketing terminology.
- Test both successful and denied operations, including attempts to access unrelated files and networks.
- Confirm how credentials are issued, rotated, revoked, and audited.
- Decide who can approve policy changes and how those changes are reviewed.
- Check that activity evidence from Learning or Permissive runs is retained according to organizational requirements.
- Integrate MXC with existing identity, device, endpoint, data-loss, and incident-response controls.
- Revalidate integrations whenever the agent, operating system, or MXC backend changes.
The practical outcome is a repeatable contract: the agent can perform a defined job, on defined resources, for a defined period, and anything outside that contract is denied or surfaced for review.
Frequently Asked Questions
Can MXC sandbox only the code an agent generates instead of the entire agent?
Yes. MXC can contain generated output, a plugin, a tool, an agent harness, or the complete agent process. Narrow wrapping can reduce the protected scope, but you must verify that helper processes and fallback execution paths do not run outside the policy.
Does MXC work on Linux as well as Windows?
The microVM option is described for Windows 11 and Linux, although it is experimental. WSL containers are the Windows 11 option for Linux-first tooling; session containers are specifically Windows 11 desktop sessions.
What happens when an organization blocks a resource the agent genuinely needs?
The workload should report the blocked operation and identify the policy-controlled resource instead of failing silently. An administrator can then review the request and grant a narrowly scoped exception, or redesign the task so it does not require that access.
Is an MXC container a replacement for endpoint detection or identity controls?
No. MXC limits runtime operations within its covered boundary, while endpoint security, identity governance, data controls, and code review address different risks. Explicitly injected credentials, broad network permissions, and processes outside the boundary remain outside MXC’s protection.
