I have been unable to get iCloud for Windows to work properly on my Windows 10 PC. The iCloud folder DOES show up in list of items in Windows File Explorer, but iCloud Photos do not. I can access the photos on my MacBook Pro, my iPhone, etc. I can even log into iCloud.com on my Windows PC and see iCloud Photos. But in Windows File Explorer ----- not at all.
I am scheduled for a call from Apple Support on Saturday afternoon, 7/25/20, so I hope that will fix the issue.
The Apple Software Update that I am referring to is mentioned in the following paragraph from an Apple Support document. The implication is that there is software that can be installed on a Windows PC which is supposed to keep Apple software updated. That was the point of the Post that you responded to.
I appreciate your response, but I'm not sure if you understood my issue. Please see the Apple Support paragraph below. The link to the entire page is: https://support.apple.com/en-us/HT201391
Update your version of iCloud for Windows
To check for updates, open Apple Software Update on your PC. To get notified when an update is available through Apple Software Update, choose Edit > Preferences, and select when you'd like to check for updates. You can choose Daily, Weekly, Monthly, or Never.
Sign out of iCloud on your PC before you upgrade and install iCloud for Windows.
