another windows 7 installation and demo prep

i think i win the geekiest airline passenger award this past week - i brought three laptops with me to redmond for the mct summit.  1 running windows 7 enterprise, 1 running windows home premium and 1 running windows server 2008 and hyper-v.  so i get out here and realize:

1) i forgot my power supply for one of the laptops

2) i need a system running windows vista enterprise

3) i still want a system running windows 7

the laptop that i forgot the power supply for is pretty standard, so i beg this evening for a power supply to get all set for the presentation friday.  i upgrade the windows vista home premium system to windows 7 and repurpose the original windows 7 as my windows vista enterprise system.
