[Feature Request][Windows] Add native “Launch ChatGPT at Windows sign-in” setting

Feature request

Please add a native setting to the ChatGPT / Codex desktop app for Windows that allows the user to automatically start the app when signing in to Windows.

Suggested options:

• Launch ChatGPT at Windows sign-in
• Optional: Start minimized / in the background

Why this is useful

The current Windows app does not expose a dedicated startup toggle in Settings. Users can work around this through Windows Startup Apps, shell:startup, or an AppUserModelID shortcut, but those approaches are external to the app and are less discoverable and less polished than a native setting.

For users who rely on ChatGPT Desktop, Codex, Computer Use, Remote Control, or long-running local workflows throughout the day, starting the app automatically with the Windows user session is useful and should be configurable from the app itself.

Expected behavior

In Settings → General (or similar), provide a toggle such as:

Launch ChatGPT when I sign in to Windows

When enabled, the application should register itself using the appropriate supported Windows startup mechanism for the Microsoft Store / MSIX package and keep working across app updates.

An additional optional setting could be:

Start minimized / in background

Platform

• Windows 11 x64
• Current unified ChatGPT / Codex desktop app
• Microsoft Store / MSIX package (OpenAI.Codex)

Related issue

#37429 mentions “Launch at login” as part of a broader request about restoring the previous workspace layout and thread state. This request is intentionally narrower: it is specifically for a first-class Windows auto-start at sign-in setting in the app’s Settings UI, independent of session/layout restoration.

Start with the Windows desktop app's Settings → General entry point and the MSIX package configuration for OpenAI.Codex. Investigate the supported Windows sign-in startup mechanism and how it behaves across app updates. Done means the setting registers or removes startup reliably, with minimized/background behavior addressed if included.
