Um, does this replace the current iCloud for Windows app that is distributed through Apple File Update? The integration, while not perfect, is something I rely on daily.
Yes it does. Now includes selective sync.
I have downloaded the version from the Microsoft Store and installed it over the Apple one. All went smoothly. No need to sign in again. Now all the items in iCloud Drive have a cloud status icon next to them and a right click option to "always keep on this device" or "free up space". This is the same as OneDrive, as in the article.
