Windows Codex settings shows Computer Use page, but plugin is unavailable and not bundled

What version of the Codex App are you using?

Windows app package:

OpenAI.Codex_26.506.2212.0_x64__2p2nqsd0c76g0

What platform is your computer?

Windows x64, Windows-native Codex app from Microsoft Store.

What issue are you seeing?

The Windows Codex app now shows a Computer Control / Computer Use settings page, but the control panel says:

Computer Use plugin unavailable

In the Chinese UI this appears as:

Computer Use 插件不可用

The page also shows an "Always allowed apps" section, but it is empty. This makes the UI look like Computer Use should be installable or configurable on Windows, but the plugin is not available.

Local diagnostics

On this Windows install, I could not find a bundled computer-use plugin in the app package or the Codex plugin cache.

The desktop logs only show latex-tectonic being written to the bundled marketplace:

[BundledPluginsMarketplace] bundled_plugins_runtime_marketplace_written pluginCount=1 pluginNames=["latex-tectonic"] targetMarketplaceRoot=%USERPROFILE%\.codex\.tmp\bundled-marketplaces\openai-bundled
[BundledPluginsMarketplace] bundled_plugins_marketplace_added marketplaceName=openai-bundled marketplacePluginNames=["latex-tectonic"] marketplaceRoot=%USERPROFILE%\.codex\.tmp\bundled-marketplaces\openai-bundled

%USERPROFILE%\.codex\plugins\cache contains installed curated plugins such as github and superpowers, but no computer-use plugin.

The user config also does not contain any explicit Computer Use plugin entry:

[plugins."github@openai-curated"]
enabled = true

[plugins."superpowers@openai-curated"]
enabled = true

[features]
memories = true

Steps to reproduce

1. Install or update Codex from the Microsoft Store on Windows.
2. Open Codex Settings.
3. Open Computer Control / Computer Use.
4. Observe that the page exists, but the control section says Computer Use plugin unavailable.
5. Check bundled plugin marketplace/logs; only latex-tectonic is present and no computer-use plugin appears to be bundled or installable.

Expected behavior

Either:

1. If Computer Use is intended to be available on Windows, the app should provide a working install/enable flow for the Computer Use plugin; or
2. If Computer Use is currently macOS-only, the Windows settings page should make that clear instead of showing Computer Use plugin unavailable, which looks like a broken local installation or cache issue.

Why this is confusing

The official Codex Computer Use documentation currently says Computer Use is available on macOS and describes macOS Screen Recording and Accessibility permissions:

https://developers.openai.com/codex/app/computer-use

The Windows Codex app documentation lists supported Windows workflows such as worktrees, automations, Git functionality, in-app browser, artifact previews, plugins, and skills, but does not list Computer Use:

https://developers.openai.com/codex/app/windows

So the current Windows UI state appears ambiguous: the settings page is present, but the actual plugin is unavailable and not bundled.

Related issues

This seems related but not identical to:

• #18258, which reports Computer Use plugin unavailable on macOS while bundled plugin files exist.
• #16574, which reports a Windows computer-use-mcp tool/schema loading problem with a custom/local MCP setup.
• #17015 / #16666, which discuss broader native GUI / Computer Use support.

This issue is specifically about the Windows Codex app showing the Computer Use settings page while the official Computer Use plugin appears unavailable/not bundled.
