Photos not going to iCloud

Thx RH,
Yes, what you say is correct. I can only tell you that in the past, up until a few months ago, everything was done automatically to the cloud on my PC. I have it synched automatically to upload and store all photos and videos in iCloud from all my devices. I now do it manually the way you described, but that’s a pain in the …so I am just wondering if Msft is not supporting Win 7 anymore for this facility as what esle could it be? Thx.
