Hi
Somthing new about Vista, ( only my opinion) if you liked getting your updates manualy and installing them manuly then vista will take all this away from you, downloading, installing ect., In Xp it always asked "do you want to download? do you want to Install now, Do you want to restart your computer, Vista does not ask you any of this, only maybe it well ask do you want to download now.
But there are settings one can do, to suit yourself.
