Thanks to those of you who tried to help. I tried the things you've suggested already. They didn't work for me. However, I discovered a neat little thing called System Restore. I used that and it worked fine. Now Windows wil open maximized.

Somewhere on the front page of this website it says to mark the problem solved if it is. I can find no place where a person can check a box that says that. I'm probably blind or looking right at it. Anyway, if someone knows how to mark this as fixed, please do so.
