This article describes the prerequisite software updates that apply to versions of Windows Vista that are mentioned in the "Applies to" section. These software updates are a prerequisite for Windows Vista Service Pack 1 (SP1). Additionally, these updates help improve reliability when you install or remove Windows Vista SP1.
Two or three additional software updates are required before you install Windows Vista SP1. The software updates that are required depend on the version of Windows Vista that you want to upgrade. Prerequisite update 935509 that is listed in this article only applies to Windows Vista Enterprise and to Windows Vista Ultimate. The other prerequisite updates that are listed in this article apply to all versions of Windows Vista.
Before Windows Vista SP1 is released, these prerequisite updates will be delivered to most users through Windows Update as part of regularly scheduled monthly updates. These updates will be installed together with other updates that will require that you restart the computer. Therefore, an additional restart will not be required. This delivery method will help simplify installation of the required updates.

The prerequisite updates will be installed by the stand-alone installer if they are necessary. The following three updates are required before you install Windows Vista SP1. However, these updates are also recommended if you do not intend to install Windows Vista SP1. These updates help improve reliability and performance when you install future individual updates from Microsoft:
