I would like to know how to modify this " A Tauri App", or where I can configure it.

It should be the shortDescription in tauri.conf.json. If it's not set it will fall back to the description property in Cargo.toml, which is set to "A Tauri App" by default.

Thanks for your answer, I did try to set shortDescription and longDescription and description , but it didn't work.

Okay, i checked it out myself and it is a bit confusing.
in tauri dev it uses the description but you have to delete a registry key for it to update after changing it (look for the app's target path in a subfolder of Computer\HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\Shell\MuiCache).
in tauri build it seems to use the app/product name, but this requires the app to be installed via the msi or setup.exe installers first.

I deleted the application data under the computer\HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\Shell\MuiCache directory.

Run tauri dev again, it's back to normal, it uses the tauri.conf.json package productName.

But there is still a problem, in tauri dev, modified tauri.conf.json package productName , it is still the previous name, not the latest change, only kill the current process, run tauri dev again, it will become the latest name.

The tauri build exe also uses the tauri.conf.json package productName .

This problem has been bothering me for a long time, thanks again for your help.
