I finally read a report on Vista and laptops... they just don't match. I upgraded some teacher's personal Vista with 2 Gb and dual core to Win 7 Pro. That poor thing could not get out of it's own mouse's way.. nothing I tried did anything. I then read a report on Vista and laptops. I had a early dual core laptop at home I upgraded to Win 7 as it just crawled all the time and the HD light would always be blinking. BINGO.. Did Win 7 fix it ! I then tried it on this teacher's laptop, again.. it was like night an day. And I did an upgrade.. not a scratch install. Amazing how bad Vista was.
I also upgrade my home PC Vista Pro to Win 7, could not believe it was the same machine. I would have not replaced it, had not it been I picked up a AMD x6 MB for dirt cheap.
