Q: Do you have iTunes installed? When you install iTunes it installs all of the iCloud support with it by default, that was when that folder showed up for me, but when I logged into my account, my Photostream showed up there. It used to say "Photostream" there, now it says "icloud photos", same thing.
I believe you can get rid of it all by removing "iCloud" - it will show up in "Add/Remove Programs and Features", if you don't want it in there, just uninstall it. You can also disable it on your device as well, if you have an Apple Device.
