"The most important note for most Windows Update users: You don’t have to change anything. The Automatic Update settings (that is, Automatically download and install, Download but let me choose when to install, Notify but don’t download, or Never check) work as they always have. The “Give me recommended updates the same way I receive important updates” check box works as it has before -- if Microsoft tags an update as “Recommended” and this box is checked, the update appears checked (ready to install) in the Windows Update list. If that box is unchecked, the update appears as unchecked in the Optional category."
