When developing Windows Vista, Microsoft set out to provide higher levels of productivity, mobility, and security, with lower costs. After more than six months of broad availability and usage, it's evident that these investments are improving the Windows computing experience. For example, in the first six months of use, Windows Vista had fewer security issues than Windows XP (Windows Vista had only 12 issues, and Windows XP had 36). According to the Windows Vista 6-Month Vulnerability Report by Jeffery R. Jones, Windows Vista had fewer security issues than all the popular operating systems he studied.
Although most companies are cautious when deploying a new operating system, many have already started testing and evaluating Windows Vista for deployment, and some have already deployed Windows Vista into their production environments and begun seeing the business benefits Windows Vista can provide.
Microsoft's efforts to provide the best Windows experience ever in Windows Vista did not end with its launch. This white paper describes the ways Microsoft strives to continuously improve Windows Vista. It then introduces Windows Vista Service Pack 1 (SP1) and describes how the service pack will fit into the ongoing improvement process.
Organizations do not need to wait for SP1 to deploy Windows Vista; they are encouraged to begin their Windows Vista evaluation and deployment now:
* Organizations currently evaluating and deploying Windows Vista should continue their evaluation, pilot programs, and deployment on the initial ("Gold") Windows Vista release. Microsoft provides the tools and guidance needed to deploy Windows Vista today and will provide additional guidance, tools and support for moving to SP1 when the service pack is released.
* Organizations just starting to evaluate Windows Vista should plan a pilot program, targeting the PCs that gain the most business value from Windows Vista (for example, many organizations will find that mobile PCs get the most benefits) and present the simplest upgrade from the gold release of Windows Vista to SP1 (How to Start a Windows Vista Pilot Deployment describes best practices for running a pilot).
* Organizations waiting for Windows Vista SP1 should start their compatibility testing on the gold release of Windows Vista now, and then begin their evaluation and pilot programs on the release candidate of Windows Vista SP1 when it is released. Windows Vista includes architectural changes relative to Windows XP that improve security and reliability. These changes can cause some applications which work on Windows XP not to work on Windows Vista. However, these architectural changes are also part of Windows Vista SP1. For this reason, testing applications on Windows Vista today will be a very good proxy for compatibility with Windows Vista SP1.
