Apple provides access to iCloud through Windows PCs, and during the past few hours, has released a beta update that adds some features to the panel.
Last September, Apple introduced a new feature for iCloud that iCloud Drive. This update has affected not only iOS and OS X Yosemite, but also Windows.
Apple has released a few hours ago the new build 410A44 iCloud beta for Windows in introducing improvements and a more correct integration with the Microsoft operating system.
Developers can download the build via the page AppleSeed testers. The public version of iCloud for Windows is instead available to download via this page.
