Microsoft recently released more detailed information about Windows Vista SP1, Nick White stated on the Vista Team Blog “We’re targeting releasing SP1 to manufacturing in the first quarter of 2008, but as always, we’re first and foremost focused on delivering a high-quality release, so we’ll determine the exact release date of SP1 after we have reached that quality bar.”

SP1 will be a large download — large enough that some businesses may want to get a DVD copy instead. - A large service pack is needed for all the changes and upgrades needed, Microsoft has identified three key areas of improvements: security, reliability and performance. Also coming are improvements to application and device driver compatibility, and administration enhancements involving deployment, management and support enhancements. Some of those upgrades have already been released but will form part of SP1.
