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.
