In a brief and, frankly, exceedingly unexpected announcement during its day two Build 2017 keynote, Microsoft announced that iTunes is coming to the Windows Store. That means anyone who buys a Windows 10 S PC, which is restricted to running apps from the Windows Store, will still be able to access Apple's full iTunes experience.

The announcement follows news from the Windows 10 S launch that Spotify will be making its way to the Windows Store as well via the Desktop Bridge. Microsoft was sure to clarify that the full iTunes experience will be available, including Apple Music streaming and iPhone syncing.

While this might not be a big deal to Microsoft followers, both Spotify and iTunes on the Windows Store are likely a pretty big deal for attracting Microsoft's target audience with Windows 10 S: Students.

While iTunes was the headliner here, Microsoft also revealed that SAP's Digital Boardroom (as a web app), Ubuntu, SUSE Linux, and Fedora will be headed to the Windows Store as well.
