OpenAI brings Codex 'Computer Use' to Windows

OpenAI extended Codex's 'Computer Use' capability to Windows, enabling the agent to directly take actions inside Windows applications rather than only generating code. OpenAI's official account framed it for Windows users specifically: 'Computer use now works on Windows, so Codex can take action on your Windows computer.' The capability is gated to eligible users in this rollout.

The companion feature is remote continuation: Windows support in the ChatGPT mobile app lets users start, review and steer Codex tasks from a phone, Mac or other device while execution continues on the Windows machine. This decouples the human-in-the-loop supervision from the execution environment, a pattern increasingly common in agentic tooling.

The release puts OpenAI's desktop-agent ambitions head-to-head with Anthropic's computer-use lineage and the broader wave of agents that operate GUIs. The competitive stakes are high in enterprise, where Windows dominates and the ability to automate legacy desktop apps is a major unlock. A cautionary signal from the community: r/OpenAI's top thread (690 upvotes) flagged that Googling 'OpenAI Codex app' surfaces a fake malware site first — a reminder that agent-on-desktop tooling expands the attack surface just as adoption accelerates.
