Windows Computer Use settings cannot find plugin; helper paths unavailable

What happened?

On the Windows Codex desktop app, Settings > Computer Use opens, but the page says it cannot find the Computer Use plugin.

The Codex app is otherwise up to date, and repair/reset/reinstall did not resolve it.

Environment

• Platform: Windows
• OS version: Windows 10.0.26200
• Codex Windows package: OpenAI.Codex_26.609.4994.0_x64__2p2nqsd0c76g0
• Codex app release observed in logs: codex@26.609.41114
• Locale: Korean (ko-KR)

Symptoms

• codex://settings/computer-use/google-chrome opens the Computer Use settings page.
• The page displays a message equivalent to: Cannot find the Computer Use plugin.
• The bundled computer-use plugin exists inside the WindowsApps package.
• The Windows Computer Use helper executable also exists inside the package, but direct execution fails with access denied.

Local diagnostics

The bundled plugin was found at a path equivalent to:

%ProgramFiles%\WindowsApps\OpenAI.Codex_26.609.4994.0_x64__2p2nqsd0c76g0\app\resources\plugins\openai-bundled\plugins\computer-use

The helper executable was found at a path equivalent to:

%ProgramFiles%\WindowsApps\OpenAI.Codex_26.609.4994.0_x64__2p2nqsd0c76g0\app\resources\cua_node\bin\node_modules\@oai\sky\bin\windows\codex-computer-use.exe

Attempting to run the helper directly fails with:

Access is denied.

Attempting to copy a bundled plugin file out of the WindowsApps package fails with:

The specified file could not be encrypted.

cipher /c reports bundled files such as plugin.json and codex-computer-use.exe as:

Compatibility Level:
  Application Protected

Steps already tried

• Confirmed Codex is up to date.
• Opened the Computer Use settings deep link.
• Repaired the Codex app from Windows app settings.
• Reset the Codex app from Windows app settings.
• Reinstalled Codex via Microsoft Store / winget.
• Restarted Codex.

Expected behavior

Computer Use settings should discover/install the bundled Computer Use plugin and locate the Windows helper paths successfully.

Actual behavior

Computer Use settings remains visible but unusable because the plugin/helper cannot be found or registered.
