Jeez, Roger Ellison, download the latest from WSUSOffline. Yes, it takes a couple of hours to complete the download (still less time than a MS Updater), but once downloaded when a newer version becomes available it only updates the changes (minutes). Transfer a copy to a flash drive and do the Win7 update installs in a matter of minutes.

And be sure to install GWX Control Panel on those old PCs before they ever see the Internet (hopefully not needed after July): http://ultimateoutsider.com/downloads/
