According to the Softpedia website, Microsoft is currently cooking the first public build of Windows Vista Service Pack 1 Release Candidate. Since the initial introduction of the first testing bits for the first service pack for Windows Vista in mid July, Microsoft has been fending off and dodging in every way possible all references to the public availability of the refresh. In terms of the final release, the company has pointed out the first quarter of 2008. And as far as a public version ahead of fully fledged service pack is concerned, Microsoft has failed breathing a single word. When it comes down to the development milestones of Vista SP1, all things are quiet over at Microsoft.
