I have a Compaq Presario xp computer. I have tried to download 11 priority windows update. It always downloads and says successful but afterwards my modem runs and runs and runs. I shut my computer down and turn it back on. I might be on for an hr. and the modem will start running like it is downloading something...or it might take 10 minutes. Someone suggested that I turn off NOrton's and I tried that and it still did the same thing. So, I find that restoring a prior date stops this but I'm back to square 1 not being able to download these updates. Can anyone help me?
