I bought Windows 7 Pro and have been trying to get everything working. My conclusion, "don't do it", lots of programs do not run correctly under Windows 7 but run perfect under XP. I will be going back to XP when I rest up from the eight hour nightmare.
Update next day
After 4 1/2 hours of reloading XP and the programs I use daily I am back to where I was before Windows 7. I think most would not have the problem I had as I do use some dedicated software in my business that you wouldn't.
