I just downloaded iTunes 64-bit and when I opened it, I allowed it to change my computer so it can work. It was called compatibility or something. Things are a little different now. Before this happened, I could run my mouse over, for example, IE and it would show screenshots of how many windows I had open. Now, after the change, it only shows lists of how many windows I have open.
I need to know how to set it all back to normal. Sorry about how confusing this sounds, too. Thanks.
