Those rumors about Windows Vista Service Pack 2 going gold in April are sounding increasingly plausible. According to Neowin, Microsoft has released an "escrow" version of the Vista SP2 and Windows Server 2008 SP2 release-to-manufacturing build to members of its Connect program.
Neowin also reported a few days back that RTM escrow builds had reached internal Microsoft testers. That report added that Vista SP2 and Server 2008 SP2 will reach proper release-to-manufacturing status next month, and that Microsoft could officially launch them at the TechEd 2009 event on May 11-15.
Based on the information Microsoft made public last year, Vista SP2 will bring a handful of major changes, including improved search, Bluetooth 2.1 support, Blu-ray recording capabilities, simpler Wi-Fi configuration, and UTC time stamps for the exFAT file system. Naturally, you can also expect the service pack to include previously released security updates and improvements.
