About Indian Rail

I'm going to travel to India for the first time. I would like to do that on train. Checked few seats and saw there are various classes. Was buying the first class (AC1) but not sure now as -- according to the various websites - the window of these classes can not be opened. Can anyone shed lights on this? Please advise on the best seat which is clean and will allow me to sightsee while on board
