Agreed! Many prefer to leave everything set for automatic however which can turn into a problem when the latest drivers
go on with the newer application portion.
That effects addon devices as well as your video, sound, softwares when a newer version is released but only part is through the updates.
For the Live Essentials however the upgrade of that when selected from the optional list with the manual option used the message to run WL. Messager was reopened to see the new wider screen and no contacts or options displayed until clicking on either the MSN or FB/Twitter button(rectangular) in the center of the initial screen.
The download and choice of only updating what was already installed was seen immediately however unlike other softwares or a full set of packages being installed where you would want to first remove everything for a totally fresh install.
