Microsoft continuously collects feedback on Windows 7 from customers and partners through several channels. This feedback results in enhancements that help improve compatibility, reliability, performance, and user experience. Service Pack integrates all these updates, along with additional enhancements, into a single package and help ensure that your systems are up-to-date.

The beta of SP1 for Windows 7 contains the pre-released 17 security updates and 456 hotfixes. The impact of SP1 on Windows 7 is considered to be minimal since it only includes pre-released hotfixes and security updates. Even though the current SP1 release is a beta, Microsoft has made it clear to not anticipate the SP1 for Windows 7 to be substantial. While SP1 is not intended to be a vehicle for releasing new features, some existing features do gain slightly enhanced functionality in SP1.

The SP1 beta has been released in English, French, German, Japanese, and Spanish. This beta will expire on June 30, 2011. You will have to upgrade to a newer build or uninstall and return to the RTM build by that time. Service Pack 1 will be released within the first half of calendar year 2011. You would not be able to upgrade from the beta builds to the final build of SP1 and will have to uninstall the Service Pack or do a clean install of Windows 7.
