Windows 11 Codex App installed from web: clarify whether auto-update exists and expose update status

What platform is your computer?

Windows 11 x64

What issue are you seeing?

It is unclear whether the Codex desktop app on Windows 11 supports reliable automatic updates.

I installed Codex from the web installer/download path, not from the Microsoft Store. From the app itself there does not appear to be a clear way to tell:

• whether automatic updates are supported for this install channel
• whether the app is currently up to date
• whether the app has already checked for updates
• whether there is a manual Check for updates action if auto-update is delayed or disabled

Because of that, when a new Codex App version is released, it is hard to know whether:

1. the web-installed app is expected to auto-update silently
2. Codex App has its own updater for this install channel
3. the current install is stuck on an older version
4. I need to manually re-download / reinstall from the website

What steps can reproduce the bug?

1. Install the Codex App on Windows 11 from the web download / installer.
2. Open Codex App.
3. Look for any visible in-app update status, current-vs-latest version info, or a Check for updates action.
4. Observe that it is not clear whether auto-update exists or is working for this install path.

What is the expected behavior?

Codex App should make update behavior explicit on Windows for web-installed builds.

For example, one or more of the following would help:

• clearly document whether the web-installed app supports automatic updates
• show whether the current app version is up to date
• provide a Check for updates action in the app
• show a banner or notice when a newer version exists but has not been installed yet
• explain whether the Microsoft Store and web-installed versions behave differently for updates

Additional information

This is primarily a Windows 11 UX / supportability issue.

I also noticed mojibake / corrupted quote characters while following up on this report, so there may be a separate Windows encoding issue somewhere in the app or reporting path as well.

If update behavior differs by install channel, the app or docs should say that clearly so users do not have to guess whether they are on the latest version.
