Thanks to the rich instrumentation capability of Windows operating systems, we are able to understand the types of issues that our customers experience while respecting their personal information and privacy preferences. This is similar in size to many common software and driver updates that are delivered by other software vendors over the internet, and therefore should not cause issues for most customers. However, most home and small business users will receive SP2 through Windows Update, which utilizes an efficient transfer mechanism to download only the actual bytes that are changed, resulting in an approximately 43 megabyte (MB) download. These features result in a large stand-alone package, which is the delivery vehicle typically used by system administrators. Also, the language-neutral design of Windows necessitates that the service pack be able to update any possible combination of the basic languages supported by Windows Vista with a single installer, so language files for the 36 basic languages are included in the standalone installer.

In order to make the improvements detailed in this document, individual files and components have been updated. In addition to all previously released updates, SP2 will contain changes focused on addressing reliability and performance issues, supporting new kinds of hardware, and adding support for several emerging standards. By providing these fixes integrated into a single service pack, Microsoft provides a single high-quality update that minimizes deployment and testing complexity for customers. SP2 is an update to Windows Server 2008 圆4 and Windows Vista 圆4 that addresses feedback from our customers and partners. Windows Server 2008 Service Pack 2 圆4 (SP2) and Windows Vista Service Pack 2 圆4 (SP2) is an update to Windows Server 圆4 and Windows Vista 圆4 that addresses feedback from our customers.
