The February Microsoft® Windows Vista™ Community Technology Preview (CTP) is the fourth in a series of early Windows Vista builds being released to an extensive technical community. The CTP program is designed to involve customers and partners in the various stages of Windows Vista development by facilitating timely and relevant feedback. The Vista CTP program will help enable Microsoft to provide testers with a feature-complete version of the product sooner than for any previous Windows® release. The February CTP offers developers, IT professionals, and Windows enthusiasts an opportunity to review and test some of the operating system’s significant security and performance enhancements and innovations. It also showcases progress on the overall user experience and design elements in Windows Vista. As with the previous CTPs, the February CTP is intended for use by developers, IT professionals and the technical community. Given the nature of software development and the feedback process, many of the features in this CTP will continue to evolve throughout the development cycle. End users interested in testing pre-release versions of Windows Vista should continue to wait until the beta 2 version becomes available. 2.7 and 3.6 GB, respectively.
