How to stop iCloud sync deleting photos on my pc?

Bought a new 2nd iPad for the kids - I deleted all photos (as Well as recently deleted photos)… But that was a mistake. What I forgot to realize is that iCloud now started deleting the photos on all my units … My PC was recently sync with iCloud so the photofolder still holds all the pictures. But when I turn it on, and I gets online with iCloud it will start to deleted them during the sync (it did so on my laptop)… how do I stop that, and keep them on my PC? I have turned on my PC but made sure it does not have any internet access. Help?
