I recently encountered an issue with my machine after someone accidentally changed the settings to what appears to be Chinese. I'm trying to revert it back to Portuguese, but I'm not quite sure how to navigate through the options. Could you please provide me with step-by-step instructions or guidance on how to change the language settings back to Portuguese? Any help or resources you could share would be greatly appreciated, as I rely on this machine for my work. Thanks!
