The latest release candidate of Microsoft's next generation OS.

This build (5744) has a number of improvements and updates from previous builds, and has been through daily testing processes to refine quality and performance. We are making this release available for a limited time only (and only by download) in order to get broad distribution and testing in a variety of PC configurations. Please note: This build may not have the same level of support or servicing via Windows Update as RC1, and you may not be able to upgrade from this build to the final version of Windows Vista.
