After getting the system up and running, I went to the Windows Update site and was directed to download (which I did) a new driver for the Athlon processor. That probably means that yes there was a bug, and now it is fixed. So far so good. The one irritant that I experienced was Microsoft's flagrant attempt to shove it's Instant Messenger Service (I have absolutely no use for these types of programs)down my throat. They don't make it easy to get rid of but I was persistant and it has been succesfully removed from my taskbar. Another question: Where is the system configuration utility hiding? Were too many people using it to disable Instant Messenger and so it was removed? All in all though, it was the easiest Windows upgrade that I have done so far.
