I received SP2 on a CD and have not yet installed it on any of my computers.
MY information is to update any and all program drivers currently in the computer before installing SP2.
Most New computers will have the newest drivers but older computers often do not have their programs updated.
I have a few more new drivers to chase down as there are Many more applications in my work computer then most have, then I will install SP2 in all the computers starting with the new lap top first as it is only occaisonal use.
