Microsoft has finally given the public Service Pack 2 for Windows Vista and Windows Server 2008 (final build is 6.0.6002.18005). You can download the installer from the Microsoft Download Center: 32-bit (348.3MB), 64-bit (577.4MB), and IA64 (450.4MB). There’s also an ISO image (1376.8MB) that contains these installers.
The installers will work on English, French, German, Japanese, and Spanish versions of either Vista or Server 2008. Other language versions will arrive later. Those interested in slipstreamed versions of Vista and Server 2008 with SP2 will need to get an MSDN or TechNet subscription.
There are a few significant additions that are included in SP2: Windows Search 4.0, Bluetooth 2.1 Feature Pack, the ability to record data on to Blu-Ray media natively in Vista, Windows Connect Now (WCN) is now in the Wi-Fi Configuration, and exFAT file system supports UTC timestamps. The service pack contains about 800 hotfixes.
More details on SP2 are available on TechNet. According to this document, SP2 is scheduled to begin arriving via Automatic Updates on June 30, 2009. If you don’t want to download the massive files from MS Download Center, try checking manually for updates on Windows Update this weekend.
