codex - 💡(How to fix) Fix Windows Codex app: Computer Use shows "Computer Use plugins unavailable" despite current docs saying Windows is supported

What happened?

In the Codex desktop app on Windows, Settings > Computer use shows:

Computer Use plugins unavailable

There is no Install button and no available Computer Use plugin to enable.

I am located in Canada / America/Toronto, not in the EEA, UK, or Switzerland. The current Codex Computer Use documentation says Computer Use is available in the Codex app on macOS and Windows outside those launch-excluded regions, and says to install the Computer Use plugin from Codex settings.

Earlier, Codex notification approvals and plugin sign-in callbacks also produced an Electron launch error:

Error launching app
Unable to find Electron app at C:\Program Files\WindowsApps\OpenAI.Codex_...\?type=action&action=1&tag=...
Cannot find module C:\Program Files\WindowsApps\OpenAI.Codex_...\?type=action&action=1&tag=...

Local process diagnostics showed launches like:

"C:\Program Files\WindowsApps\OpenAI.Codex_...\app\Codex.exe" type=action&action=1&tag=...

The Windows app package was re-registered and later updated, but Computer Use is still unavailable.

Expected behavior

Codex Settings > Computer use should show an Install button for the Computer Use plugin, or explain why the current account/workspace/platform is not eligible.

Environment

• Codex package: OpenAI.Codex_26.602.3474.0_x64__2p2nqsd0c76g0
• Codex version: 26.602.3474.0
• OS: Microsoft Windows 11 Home
• OS version: 10.0.26200
• Build: 26200
• Time zone: Eastern Standard Time
• Start app entry exists: OpenAI.Codex_2p2nqsd0c76g0!App
• codex: protocol key exists under HKCU:\Software\Classes\codex

Additional context

In the active Codex session, tool/plugin discovery does not expose Computer Use.

The installable plugin/connector list includes BioRender, Figma, Google Drive, Hostinger, Hugging Face, Linear, Netlify, OpenAI Platform, Ranked AI, Slack, Vercel, Notion, Outlook Calendar, Outlook Email, SharePoint, and Teams, but does not include Computer Use.

This appears related to, but possibly distinct from, prior Windows Computer Use reports:

• #21692: Windows Codex settings shows Computer Use page, but plugin is unavailable and not bundled
• #22951: computer use/chrome plugin completely disappeared from codex
• #25301: Computer Use unavailable in Windows Desktop when app-server runs in WSL
• #25512 / #25571: Windows Computer Use installed/enabled but native connection/helper paths unavailable

The current case is specifically: current Windows Codex app, current docs say Windows is supported, but the Computer Use plugin is not exposed/installable at all.
