Why would my windows and data "computer" stop working at same time?

What is your question?

I let my car sit for several monthes and the battery died. I had to get a new battery and all was great until I noticed now none of my windows will roll down and oddly the data "computer" that shows time/temp etc isn't working either. I am sure both happened at same time. I checked fuses but couldn't find problem. Help!?!
