The Windows Update Experience Systems running on Windows Vista RTM typically require two or three updates before SP1 can be installed. These updates are permanent on your Windows Vista systems. Windows Update will detect your system configuration and offer the prerequisite packages that are applicable to your system. Based on the state of your system, Windows Update will offer you all the applicable prerequisite packages and SP1 in a sequential order. For details, please see the instructions below. The prerequisite updates consist of two updates which service specific Windows components prior to the installation of the service pack and a third update which services the installation software built into Windows Vista. The following are the prerequisite updates.
Installing the Service PackThere are two ways to install the service pack, first, as a pop-up notification that the service pack is ready to be installed (this is the method in which most users will install the service pack) and using multiple manual installations from Windows Update. The first method is the simplest, but may take up to four days for the Windows Update Automatic Update feature to deliver each of the 3 prerequisites and the service pack.
