What version of the Codex App are you using (From “About Codex” dialog)?

标题：Windows 电脑控制插件无法读取窗口，授权后仍返回 EPERM 环境： - Windows - Codex 桌面应用 - 电脑控制组件版本：26.803.81509 - 问题至少从 2026-08-12 持续至 2026-08-13 复现步骤： 1. 在 Codex 中请求使用电脑控制插件列出当前打开的窗口。 2. 插件调用 sky.list_windows()。 3. 运行立即失败，尚未读取到任何窗口。 错误信息： EPERM: operation not permitted, lstat 'C:\Users\1\AppData\Local\OpenAI\Codex' 补充诊断： - 已明确授予 C:\Users\1\AppData\Local\OpenAI\Codex 的读取权限。 - 授权后重置运行环境并再次调用，错误完全相同。 - 对该路径执行只读检查同样返回 Access is denied。 - 已多次重启 Codex，问题仍然存在。 - 插件没有切换、关闭或更改任何窗口。 预期结果： sky.list_windows() 应返回当前可控制窗口的列表，不应因 Codex 自身应用目录的访问权限而失败。 请重点检查 Windows 沙箱向电脑控制 Node 运行库传递文件系统权限的流程。

Title: Windows computer control plugin cannot read windows and still returns EPERM after permission is granted Environment: - Windows - Codex desktop app - Computer control component version: 26.803.81509 - The issue has persisted from at least 2026-08-12 through 2026-08-13 Steps to reproduce: 1. In Codex, request that the computer control plugin list the currently open windows. 2. The plugin calls sky.list_windows(). 3. The run fails immediately, before any windows are read. Error message: EPERM: operation not permitted, lstat 'C:\Users\1\AppData\Local\OpenAI\Codex' Additional diagnostics: - Read permission for C:\Users\1\AppData\Local\OpenAI\Codex was explicitly granted. - After granting permission, the runtime environment was reset and the call was attempted again, but the error was exactly the same. - A read-only check on that path also returns Access is denied. - Codex has been restarted multiple times, but the issue persists. - The plugin did not switch, close, or modify any windows. Expected result: sky.list_windows() should return a list of currently controllable windows and should not fail because of access permissions for Codex's own application directory. Please focus on checking the process by which the Windows sandbox passes filesystem permissions to the computer control Node runtime.

Steps to reproduce:

  1. In Codex, request that the computer control plugin list the currently open windows.
  2. The plugin calls sky.list_windows().
  3. The run fails immediately, before any windows are read.

Error message:
EPERM: operation not permitted, lstat 'C:\Users\1\AppData\Local\OpenAI\Codex'

Additional diagnostics:

  • Read permission for C:\Users\1\AppData\Local\OpenAI\Codex was explicitly granted.
  • After granting permission, the runtime environment was reset and the call was attempted again, but the error was exactly the same.
  • A read-only check on that path also returns Access is denied.

I hope Codex can take control of my computer.

I encountered a very similar issue on Windows 11 25H2, but with a different failure point.

Environment:

  • Windows 11 Home
  • OS build: 26200.8875
  • ChatGPT/Codex Windows desktop app
  • Computer Use / Windows sandbox enabled

Symptoms:
Computer Use cannot start because the sandbox helper fails with permission errors.

Relevant logs:

codex-command-runner runner exit write failed: os error 232
hide users: failed to hide current user profile dir (C:\Users\Default):
SetFileAttributesW failed for C:\Users\Default:
5 (Access is denied)

Additional observations:

  • Reinstalled Codex desktop app
  • Restarted multiple times
  • Confirmed the runner executable exists:

.codex\sandbox-bin\codex-command-runner-0.147.0-alpha.6.6.exe

  • Windows Defender "Controlled folder access" is disabled
  • The issue persists after permission checks

The failure seems related to Windows sandbox permission handling / ACL configuration.

Hope this additional Windows 11 25H2 reproduction case helps debugging.
