1. The touchpad I know isn't a driver issue. Just the left click doesn't really work, and the right works a bit better. I mean who knows, I never really tried much to fix it, this laptop was heavily used by my Mom before I got it.
2. Bluerobot, Windows 7 and XP weren't originally shipped with this series of vaio's. They were added due to popular request according to them, Just for whatever reason the windows 7 drivers they barely have any, despite recommending people switch to it. But placehold drivers is a good way of explaining it. So that answered a question.
3. lol I know what directx is. But I thought having higher versions of directx could make previous directx versions run better, or fix any issues. But I assume going from 9 to 10 is not the same as 9a to 9c.
