## Why The elevated Windows sandbox persists dedicated sandbox account credentials so later commands can launch without reprovisioning. If those persisted credentials drift from the actual Windows account password, `CreateProcessWithLogonW` fails with `ERROR_LOGON_FAILURE` and Codex currently surfaces that as a hard runner launch failure. This change makes that failure self-healing. When Windows specifically rejects the sandbox login, Codex now treats the persisted sandbox credentials as stale, regenerates them through the existing setup path, and retries the runner launch once. ## What Changed - Preserve `CreateProcessWithLogonW` failures as a typed runner logon error so callers can distinguish `ERROR_LOGON_FAILURE` from unrelated launch failures. - Add a sandbox credential refresh helper that deletes the persisted `sandbox_users.json` record and reuses `require_logon_sandbox_creds()` to reprovision credentials through the established setup flow. - Retry elevated runner startup after stale-credential failures in both the legacy elevated capture path and unified exec elevated backend. - Add focused tests for stale logon failure detection and persisted sandbox user file removal. ## Validation - `git diff --check` - `cargo test -p codex-windows-sandbox`
Codex CLI is a coding agent from OpenAI that runs locally on your computer.
If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run
codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.
Quickstart
Installing and running Codex CLI
Run the following on Mac or Linux to install Codex CLI:
curl -fsSL https://chatgpt.com/codex/install.sh | sh
Run the following on Windows to install Codex CLI:
powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"
Codex CLI can also be installed via the following package managers:
# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex
Then simply run codex to get started.
You can also go to the latest GitHub Release and download the appropriate binary for your platform.
Each GitHub Release contains many executables, but in practice, you likely want one of these:
- macOS
- Apple Silicon/arm64:
codex-aarch64-apple-darwin.tar.gz - x86_64 (older Mac hardware):
codex-x86_64-apple-darwin.tar.gz
- Apple Silicon/arm64:
- Linux
- x86_64:
codex-x86_64-unknown-linux-musl.tar.gz - arm64:
codex-aarch64-unknown-linux-musl.tar.gz
- x86_64:
Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.
