The official Codex desktop app from OpenAI is your command center for agentic software development. With the Codex app you can: - Multi-task with agents — Run multiple coding agents in parallel, organized by project and thread - Keep work...

With the Codex app on Windows, now you can: • Work with multiple agents in parallel • Manage long-running tasks • Review diffs in one place • Stay in your existing setup, without switching to WSL or VMs

To bring Codex to Windows, OpenAI built their first Windows-native agent sandbox.

It uses OS-level controls like restricted tokens, filesystem ACLs, and dedicated sandbox users so agents can safely run in real Windows developer environments like PowerShell.
