Environment
- Codex Desktop: 26.730.61639
- OS: Windows
- Computer Use plugin: enabled
- Runtime: cua_node
- Project path: D:\系统默认\文档\New project
Problem
Computer Use cannot enumerate Windows applications or windows.
Error
EnumWindows failed: 系统找不到指定的路径。 (0x80070003)
Diagnostics
- @oai/sky imports successfully
- codex-computer-use.exe exists and starts successfully
- Helper runs in the interactive user Session 1
- Named pipe exists and is accessible
- Resetting the Node REPL does not help
- Restarting the helper process does not help
- Codex installation location does not appear to be the cause
- The issue reproduces with both list_apps() and list_windows()
Expected behavior
list_apps() and list_windows() should return the current Windows applications/windows.
Actual behavior
Both calls fail immediately with EnumWindows error 0x80070003.

Related report from another Windows task on the same app/plugin build: Computer Use failed before a desktop application could be controlled. The first attempt to open NetEase Cloud Music returned
spawn EPERM, and resetting/retrying did not restoresky.list_apps()orsky.list_windows(). I did not observe 0x80070003 in that task, but the failure also occurs before a target app is selected, which may help correlate the different Windows helper failure stages.
