Microsoft will offer the first Release Candidate of Service Pack 2 for Windows Vista in February 2009. Vista SP1 was of course released to manufacturing on February 4, 2008, concomitantly with the RTM of Windows Server 2008. Come April 2009, the software giant reportedly plans to sign-off the code for Vista SP2. As it happened with SP1, the RTM and availability deadlines for Vista SP2 might not coincide. Vista SP1 RTM'd in February but was only up for grabs in mid-March 2008, reports TechARP.
