In a rare show of cooperation, Microsoft and Apple are working together to keep iCloud of Windows 10 October 2018 update.
The issue is an incompatibility between the latest version of Windows 10 and the latest version of the iCloud software, version 188.8.131.52.
Microsoft is keeping us up to date with the issues they encounter during the roll-out of the Windows 10 October 2018 update and reports:
Apple has identified an incompatibility with iCloud for Windows (version 184.108.40.206) where users may experience issues updating or synching Shared Albums after updating to Windows 10, version 1809. Users who attempt to install iCloud for Windows (version 220.127.116.11) on Windows 10, version 1809 will see a message stating that this version of iCloud for Windows is not supported, and the installation will fail.
To ensure a seamless experience, Microsoft is blocking devices with iCloud for Windows (version 18.104.22.168) software installed from being offered Window 10, version 1809 until this issue has been resolved. We recommend that you do not attempt to manually update using the Update Now button or the Media Creation Tool from the Microsoft software download website until this issue is resolved.
Next Steps: Microsoft is working with Apple to provide a compatible version of iCloud for Windows 10, version 1809 in an upcoming release.
It is somewhat interesting that this issue was only detected after the roll-out started, and suggests Insiders are as reluctant as everyone else to install Apple's software on their PCs.
