how to determine which version of icloud for windows do i have

Hello stephenfromriver ridge,

Welcome to Apple Support Communities. 

We recommend checking in the Microsoft App Store in the description section or About section of the app.

Here’s additional information about downloading iCloud for windows: Download iCloud for Windows - Apple Support

Take care.

With iCloud for Windows...

1. Apple seems to provide no way to check within the app to determine its version
2. It provides no way to check for updates or ensure it has automatic updates going

It is sad to see the recommendation is to check with Microsoft. As of today (11/22/22) the MS Store reports the latest version was published 2/1/2019. I doubt that is the latest update.

Simply horrible.
