Windows Vista Service Pack 1 is yet to reach the end of its journey, but the resources associated with the service pack have been made available ahead of the completion of the rolling-out process. Released to manufacturing on February 4, 2008, Vista SP1 took another month and a half before making its way to end users. March 18 marked the date when the service pack was delivered via Windows Update and the Microsoft Download Center. Just three days later Microsoft started offering the revamped Windows Vista Product Guide. Initially dropped with the RTM build of Vista, the Product Guide has been tweaked in order to accommodate the modifications introduced with the service pack.

"Windows Vista SP1 is a continuation of Microsoft's and its partners' drive to provide the best experience possible. The goal is to address key feedback that Microsoft has received from its customers, without regressing application compatibility. SP1 delivers improvements and enhancements to existing features that significantly affect customers, but it does not deliver substantial new operating system features. For example, the service pack improves file-copy performance but does not include a new version of Windows Explorer. The updates in SP1 fall into three categories: quality improvements, new hardware and standards, and infrastructure optimization," reads an excerpt of the Vista SP1 Product Guide.

Only in April 2008 will Microsoft start offering Windows Vista SP1 through Automatic Updates to all Vista RTM users that have AU enabled on their machines. This month will also bring to the table the RTM date of the remaining language editions of Vista SP1. In the Wave 0 release on March 18, Microsoft offered the service pack only to Vista users running the platform in English, French, German, Japanese and Spanish. For the time being, only the users of Vista copies in the languages mentioned above can get their hands on SP1. The Windows Vista Product Guide has additional details, but at the same time Microsoft is also offering the Windows Vista Product Guide Revision Document, a resource designed to outline the enhancements of SP1.

"Of the improvements in Windows Vista SP1, quality improvements have the biggest impact on all customers-business or consumer. Quality is the foundation of SP1 and is about improving the overall Windows Vista experience. SP1 includes all previously released updates for Windows Vista and specifically targets issues that Microsoft has identified as the most common causes of operating system failures, thus giving customers a more reliable experience. SP1 also improves the operating system's performance and security. For example, SP1 can reduce by as much as half the time to copy a large collection of files," it is added in the Vista SP1 Product Guide.
