If you don’t use them, they can’t be uninstalled the same way they can be uninstalled in the regular way. In Windows 10, folder names like Camera Roll and Saved Pictures are automatically selected.
You can disable the auto-sync feature, or you can delete the Camera Roll folder from your Picasa web album. This is a convenient way to backup your photos, but it can be annoying if you don’t want Picasa to automatically sync your photos. When you take a picture with your Android phone, the image is automatically saved to the “Camera Roll” folder in the Picasa web album.
