Microsoft has restarted the rollout process for its Windows 10 October 2018 Update, but it appears that some people are finding they cannot use iCloud after installing the update.

If users try to install the latest version of iCloud for Windows 10, version 7.7.0.27 with the October 2018 Update already installed, an error message appears saying that “iCloud for Windows requires Windows 7, Windows 8, or Windows 10 (April 2018 Update) and earlier”.

If Apple users already have the app already installed, then you may find there are several issues when using the software to sync your files and photos with Apple’s cloud storage service.

Microsoft is working with Apple to fix these problems, but for now, it looks like Windows is off limits to those who want to upload their cat pictures and Coldplay collection to the iCloud.

In a post on the Windows 10 Update support website, Microsoft has noted that “Apple has identified an incompatibility with iCloud for Windows (version 7.7.0.27) where users may experience issues updating or syncing Shared Albums after updating to Windows 10, version 1809”.

Version 1809 is the October 2018 Update. For the moment, Microsoft is “blocking devices with iCloud for Windows (version 7.7.0.27) software installed from being offered Window 10, version 1809 until this issue has been resolved”.

So, if you have iCloud already installed, you’ll find you're unable to install the October 2018 Update for the time being. It's annoying but better than finding your folders and files are no longer syncing properly with iCloud.

Microsoft claims that it is working with Apple to create a compatible version of iCloud for the October 2018 Update, which will be included in an upcoming release. Curiously, neither Apple nor Microsoft are claiming the issue only affects a small number of users who are holding their Windows 10 machines in the wrong way.
