Based on Microsoft’s partnership with Apple, Apple has ported iTunes UWP version last year and released it to the Microsoft Store for Windows 10 users to download. There is also software on the Windows 10 platform that many users need, and that is Apple Cloud Service Suite iCloud for Windows.
According to the latest news from WalkingCat, Apple seems to have developed the iCloud UWP version and is about to release it to the app store for users to use.

As for when the user can download and use the fastest, it is not clear, but interested users can follow the follow-up news of the iCloud UWP version.
