As one Microsoft official acknowledged last week, Microsoft has begun making the second service pack for Vista and Windows Server 2008 available to the public on May 26.
Microsoft is expected to begin pushing SP2 to users via Windows Update on June 30, according to the aforementioned company official.
Update (May 27): Some users already are finding Microsoft is pushing SP2 to them via Windows Update. On the Microsoft Springboard blog, Microsoft officials noted that the company has begun pushing SP2 automatically. (Information about how users who aren't ready for SP2 can block it using the Microsoft blocker toolkit is part of that post.)I understand Microsoft execs are trying their best to downplay Vista, due to the imminent arrival of Windows 7, but the conflicting and confusing information coming from Microsoft about Vista SP2 has been ridiculous -- almost as bad as the way the company communicated information around Vista SP1.
Microsoft released SP2 to manufacturing on April 30 and has been telling customers it would deliver the final SP2 bits to the public before the end of the second quarter of 2009, declining to provide further specifics.
