Delete photos from shared albums in iCloud
When you delete a photo or video from a shared photo album, it’s removed from the shared album on all your devices and all subscribers’ devices.
On a Mac using Photos
See Add, remove, and edit photos in a shared album in Photos on Mac in the Photos User Guide.
On a Windows computer

In the iCloud for Windows app (version 7): Open File Explorer (Windows 8 or later) or Windows Explorer (Windows 7), select iCloud Photos, then double-click Shared.
Double-click the shared album you want to delete photos or videos from.
You can’t delete from the Activity view.
