Wow... 3 double posts in one posts. :O. So many.
Wait, so you're running windows vista and you can't find your home key? O.o... How does that relate?
If you're looking for you home key, take your right hand, move it until you find the numpad. The home key is the number 7 key on the right side of your numpad. It is NOT f7 or the 7 key above the letters (main keyboard).
