The latest Codex app update arrived on May 29, 2026, bringing computer use capabilities to Windows users. OpenAI designed this release, version 26.527, to allow the application to control a user’s computer using its own cursor. Consequently, developers can now automate tasks across various desktop applications that lack native APIs.
Unlike the macOS version, this feature operates strictly in the foreground on Windows. Therefore, users cannot work in the same Windows session while the agent controls another application. Specifically, the tool operates by viewing the screen, clicking buttons, and typing text to complete tasks. This is useful for testing applications and reproducing bugs in the user interface.
New Features in the Codex App Update
This Codex app update also introduces remote control capabilities for Windows devices. Users can connect their PCs to the ChatGPT mobile app on iOS and Android. Meanwhile, this connection allows developers to start new threads, approve actions, and review test results remotely using artificial intelligence tools.
Profile Enhancements and Technical Specifications
In addition, OpenAI updated the profile section to display usage statistics and token activity on Windows computers. The application runs natively on Windows using PowerShell and the Windows sandbox. Alternatively, developers can configure the software to run in Windows Subsystem for Linux 2. Meanwhile, the application is available through the Microsoft Store and supports core workflows like Git functionality and artifact previews.
Broader Context and Platform Parity
Previously, these computer use capabilities were exclusive to macOS users. However, this release brings the software to parity with competing tools like Cursor, Cline, and Claude Code. Notably, OpenAI reports that more than 3 million developers use the platform weekly to accelerate work across the software development lifecycle.
Furthermore, the update includes several improvements to the mobile experience. Specifically, the iOS application now supports side conversations, archived remote threads, and one-tap model switching. As a result, developers can manage their workflows more efficiently from mobile apps.
Future Outlook for Windows Developers
The Codex app update represents a significant expansion for Windows-based developers. By offering a single interface for parallel agent threads, the tool simplifies complex development workflows. Consequently, the company expects broader adoption of its agentic capabilities across different operating systems.
