In a post on the Windows 10 Update support website, Microsoft has noted that "Apple has identified an incompatibility with iCloud for Windows (version 126.96.36.199) where users may experience issues updating or syncing Shared Albums after updating to Windows 10, version 1809, that means inspite of Microsoft restarting the rollout process for its beleaguered Windows 10 October 2018 Update, it appears some problems are persisting, as users are finding it difficult using iCloud after installing the update.
For users that already installed the app, they tend to find out several issues when using the software to sync files and photos with Apple's cloud storage service while users that are yet to install the latest version of iCloud for Windows 10 version 188.8.131.52 with the October 2018 Update already installed see an error message comes up saying "iCloud for Windows requires Windows 7,Windows 8, or Windows 10 (April 2018 Update) and earlier. The Version 1809 is the October 2018 Update. For the moment, Microsoft is "blocking devices with iCloud for Windows (version 184.108.40.206) software installed from being offered Window 10, version 1809 until this issue has been resolved."
This is a frustrating issue for both, but the good news is that Microsoft is working with Apple to fix these issues,as Microsoft claims that it is working with Apple to create a consistent version of iCloud for the October 2018 Update, which will be enclosed in the upcoming release. Hopefully, we expect a new release soon
