Windows appears in minimized form

I must love to make mistakes, maybe because I have the chance to talk to those who can solve them. Somehow or other I have clicked or punched a button that has resulted in minimized windows for my Home Page each time I go on line, for My Documents and for my email. I have looked and peered around corners and into files and did not see anything I thought would correct it. Please point my 'lil old hairless head (I have a problem typing 'bald') in the right direction and I will thank you very much. Woody
