iCloud back up still restoring

I restored my iPhone from iCloud last night and the only thing I can find is a section of photos in 'All photos' that have not loaded yet, this is causing my phone to still say 'restoring from iCloud backup' on the lock screen, it is now 19 hours or so since I started the restore and it is still in the same predicament, I looked at downloading iCloud to my computer to ensure that I had a copy of the missing photos somewhere, but iCloud for windows is not compatible with the version of windows I have. I have also in the mean time deleted a load of different things (apps, old message conversations, data, etc) of my phone to ensure that there is enough storage left for my phone to store said missing photos. I have forced a back up to my computer in the mean time, knowing however that the chances of the photos being in the restore will be there are rather slim, but felt best to have a back up somewhere since it wont back up to iCloud whilst trying to restore from iCloud. Now, I don't know if I should just leave it to keep trying to download them, stop the restore, or what, it has been left overnight (for a good 7-8 hours) not being used but still on and connected to power and to a strong wifi.

Is there a way to get the photos with out stopping the restore, or do I need to just start again, or just leave it?
