Codex Windows Fast Patch

Use this skill when the user says Codex Desktop was upgraded and the Fast Mode / Plugins / Goal patch disappeared, asks to repatch Codex on Windows, asks to verify whether Fast Mode is really being sent, asks to restore/register the local plugin marketplace, asks to enable Chrome browser use or Windows Computer Use in Codex Desktop, or asks to enable/repair phone remote control while keeping third-party/API-key model access. Also use it when a custom provider or /v1/models exposes a new model but Desktop still hides it, when GPT-5.6 Sol/Terra/Luna are missing from the model picker, when the compact blue-purple Power slider falls back to the legacy Model / Reasoning / Speed menu because Statsig available_models filtering removed the required model combinations, or when the "Ultra in model picker slider" setting is visible but disabled because a third-party provider cannot load ChatGPT account user settings. Also use it when the language/locale setting reverts after restart, browser or plugin entries are hidden by availability gates, the Computer Control settings page shows "Any App" / "任意应用" as disabled by organization or unavailable in the current region, a Computer Use task reports native pipe, bundled plugin cache, helper path, package import, or runtime initialization errors, a Computer Use conversation loses cua.getApp / cua.listApps while cua.getState() and the native pipe still work and the symptom returns after every Desktop restart, a Computer Use call fails with Native app bindings are unavailable for windows. or times out on an in-app-browser tab while cua.computer.list_windows() still works, phone remote-control QR pairing spins/fails, post-pairing phone-created turns hit the wrong model API endpoint, Desktop new-chat/thread start fails with missing field inputSchema, local conversations disappear after switching model_provider / API account, restored conversations are visible but cannot continue because the current working directory is missing, or the user explicitly asks to configure the bundled custom model_instructions_file prompt asset.

Platform Compatibility

This skill is Windows-only. It depends on the Windows Store/MSIX package layout, PowerShell, Get-AppxPackage, makeappx.exe, signtool.exe, Windows user environment variables, and Windows Computer Use helper paths.

Do not run this skill on macOS. A macOS adaptation needs a separate workflow for the Codex .app bundle, ASAR extraction and repacking, macOS code signing or quarantine handling, shell scripts, and macOS-specific Computer Use availability.
