Note: The way I have mine set is to only notify me that updates are availiable, but to not download them automaticaly. Then I can check to be sure I get just the ones I want. I then click on “custom”, and after the updates have been downloaded I look them over to see which ones I want, then disconnect from the net, disable firewall and anti-virus program, and then install the updates, and then re-enable the firewall and the free antivirus protection programs before reconnecting to the net. = http://support.microsoft.com/kb/306525
