codex - 💡(How to fix) Fix Windows 10 Computer Use screenshot fails: SetIsBorderRequired failed (0x80004002)

Summary

On Windows 10 Pro 22H2, Codex Desktop Computer Use can connect to the Windows Computer Use helper and perform non-screenshot operations such as listing windows/apps, reading accessibility text, activating a window, and sending keyboard input. However, any Computer Use path that requests a screenshot fails with:

SetIsBorderRequired failed: 不支持此接口 (0x80004002)

This appears to be a Windows 10 compatibility issue: the helper calls GraphicsCaptureSession.IsBorderRequired / SetIsBorderRequired, but this API is documented as introduced in 10.0.20348.0, while current Windows 10 client 22H2 is build 19045.

Environment

• Codex Desktop install source: Microsoft Store
• Codex Desktop version: 26.527.3686.0
• Computer Use plugin/cache version observed: 26.527.31326
• OS: Windows 10 Pro 22H2
• OS build: 19045.6466
• Get-ComputerInfo: WindowsProductName=Windows 10 Pro, OsBuildNumber=19045
• HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion: DisplayVersion=22H2, CurrentBuild=19045, UBR=6466

What works

After connecting to the existing Computer Use named pipe, the following operations work:

• sky.list_apps() succeeds and returns applications.
• sky.list_windows() succeeds and returns active windows.
• sky.get_window_state({ include_screenshot: false, include_text: true }) succeeds for at least Microsoft Paint and returns an accessibility tree.
• sky.activate_window(...) succeeds.
• sky.press_key(...) succeeds.

Example window enumeration included a Weixin/WeChat window:

{
  "app": "process:K:\\Applications\\Weixin\\Weixin.exe",
  "id": 854470,
  "title": "微信"
}

What fails

Requesting a screenshot through Computer Use fails. Example call:

await sky.get_window_state({
  window: targetWindow,
  include_screenshot: true,
  include_text: false,
});

Observed error:

SetIsBorderRequired failed: 不支持此接口 (0x80004002)

This blocks Computer Use screenshot-based workflows and coordinate input that depends on a fresh screenshot. Accessibility-only reads still work when the app exposes useful UIA text, but apps such as Weixin/WeChat expose only a render container (MMUIRenderSubWindow), so screenshot support is required for practical use.

Expected behavior

On Windows 10 build 19045, Computer Use should either:

1. avoid calling SetIsBorderRequired / IsBorderRequired when that interface is unavailable, and continue capture with the default capture border behavior; or
2. clearly report that screenshot capture requires a newer Windows build, while keeping non-screenshot Computer Use operations available.

Actual behavior

Computer Use screenshot capture fails with SetIsBorderRequired failed: 不支持此接口 (0x80004002), even though the helper pipe and non-screenshot operations are otherwise usable.

Suspected cause

Microsoft documents GraphicsCaptureSession.IsBorderRequired as introduced in device family version 10.0.20348.0 / UniversalApiContract v12. Windows 10 Pro 22H2 client is currently build 19045, so calling this property appears to return E_NOINTERFACE (0x80004002).

The helper likely needs a runtime API/contract check and fallback path that skips SetIsBorderRequired on older Windows 10 client builds.

Related issues

These look related to Windows Computer Use helper/native-pipe availability, but this issue is specifically about the second-stage screenshot failure after the helper is reachable:
