Issues with icloud Photo Library(32 bit)

I am using Windows 10 and I have the Icloud software install.

I received notification that I had reached 90#% of my wifi limit (1024 gb) on November 6th. In doing some research it appears the above mentioned process is constantly using significant amounts of Network bandwidth (I killed it) and we stopped using significant amounts of bandwidth. However on reboot we went back to using lots of network bandwidth. Fortunately my provider gives me two months going over until I get charged and this is the first. Most months I use less than 200GB.

Any thoughts on what could be causing this.
