At WWDC 2019, Apple announced it would kill iTunes. iTunes is being replaced by separate apps for music, television and podcasts – but only on macOS. Windows users retain the latest iTunes app that they know and (often) do not love.

But what about Windows? Apple did not mention iTunes for Windows at all. According to Billboard's Micah Singleton, Apple has informed him that iTunes will continue to exist in its current status under Windows.
Apple has informed me that iTunes will still be available in its current status under Windows and the iTunes Music Store will be available in the Finder's sidebar under MacOS Catalina

Brian Barret of Wired is working on this report, reporting that "iTunes for Windows [will] is still in its current state."  That's either good news or bad news, depending on what you were hoping for. If you're looking for a shiny new Apple Music app for Windows, stay with iTunes. If you liked the old iTunes experience, it will not disappear. The classic iTunes software, with all its quirks and powerful features like local device backups, will continue to be available on Windows.
