Photos syncing only work with the same Apple ID with different devices. To sync iCloud photos, you need to make sure the iCloud Photos feature is enabled and you need to allow the PC to download new photos and videos.
Generally, there are 4 reasons making iCloud syncing failure: However, the uploading process may suddenly stop and prompt you “photos excluded (not synced)” or “iCloud photos not syncing” or something like that during the process. Lots of people upload their photos on their Windows 10 computers to manage and view pics, and videos on their Apple devices with their Apple ID. Question from Why iCloud photos not syncing to Windows 10? Why can't I transfer photos from iPhone to Windows PC? Any ideas? Thanks.
And the program says “Excluded (not synced)”. But only about 3GB of photos were uploaded, and the rest are not synced. I have a lot of images that are about 4GB, and I tried to move them to my iCloud drive on my Windows 10 PC.
