What is a standalone vs. an integrated SP2 DVD?
An integrated installation (also known as “slipstream installation”) means that the service pack is integrated into the operating system, and therefore the operating system and service pack are installed simultaneously. You can use the integrated installation to upgrade computers running Windows XP and to perform clean installations on computers that do not have an operating system. A standalone SP2 DVD, also known as a ‘Patch DVD’, you use the stand-alone pack to upgrade computers that already are running the Windows Vista operating system with Service Pack 1 level installation. The download size of the stand-alone package is larger than the package applied with Windows Update. This method is recommended for: 1) Applying Windows Vista SP2 to computers without (or with limited) Internet connectivity 2) Applying the service pack to more than one computer using deployment tools such as Systems Management Server 2003 (SMS) or System Center Configuration Manager 2007.
