OK, folks, back up your systems, and get ready for the update! I would recommend doing an image backup (Start/Control Panel/System and Security/Backup and Restore/Create a System Image) before deploying the SP1 for Windows 7, regardless of the version. You can get the Technet information here: (http://technet.microsoft.com/en-us/library/ff817622(WS.10).aspx), and an easier to read summary on the service pack here: (http://www.eweek.com/c/a/Windows/Microsoft-Polishes-Desktop-OS-101452/).
