Apple has released Apple Releases iTunes for Windows Update With Option to Listen to Podcasts and Audiobooks / MacRumors iTunes Windows update 12.13. It allows you to listen to podcasts and audiobooks — provided that Apple Music and Apple TV are installed on the computer.
iTunes updates are quite rare right now. On macOS, the app was replaced by the Finder and TV apps a few years ago, but Apple continues to support the Windows version. The previous update was released in September, but then they just added support for the iPhone 15.
You can download iTunes for Windows from the Microsoft Store or from the official Apple website (at the time of publication, the latest update on the site is not yet available).
