I went with my cousin about 10 years ago. I was a Mission Specialist and got to do the EVA. He was stuck in ground control. It was a tense plane ride home :-)
But clean install of Windows 7 or 8 + ninite.com. Windows generally has the drivers you need out of box, or at least the NIC / wireless driver so Windows update can find the rest for you, automatically. I can't remember the last time I had to manually get a driver for something, with the single exception of a USB to serial adapter I need for work.
