iTunes is finally available for download from the Microsoft Store for Windows 10 computers.

Microsoft originally announced iTunes for its Windows 10 app store a year ago at its annual Build developer conference. The app was supposed to launch by the end of the year, but quietly missed its release. Bet you didn't even notice, did you?

iTunes has long existed on Windows and it's not like Windows 10 users couldn't download and install the app from Apple.

The app's arrival in the Microsoft Store is more significant for Windows 10 S users, whose computers can't install apps from anywhere but Microsoft's official app store.

Windows 10 S was originally pitched as a special version of Windows 10 designed for educational institutions. It's still mostly the full Windows 10 experience, but more secure because users can't install non-approved apps willy-nilly and potentially download a virus or malware.

Surface Laptop users who didn't take advantage of their free Windows 10 Pro upgrade finally have a way to download and access music and videos they've purchased from iTunes, stream Apple Music, and connect their iOS devices for backup.

The 17-year-old app has been criticized for becoming bloated as new features are tacked on. Many critics have urged Apple to redesign it or break it up into several apps. You could argue that iTunes isn't necessary anymore when the App Store, iTunes Store, iCloud, and Apple Music exist, but you'd be surprised at how many people still prefer to backup their iOS devices or manger their music the old-fashioned way.

However you feel about iTunes, its release on the Microsoft Store is better late than never.
