With today's launch of the Customer Preview Program (CPP) for Windows Vista® Service Pack 2 (SP2), we wanted to provide a brief synopsis of the elements in this service pack, and encourage you to download and test this release. Windows Vista SP2 is a traditional service pack release with all cumulative released security updates available since the SP1 release in March 2008. In addition, Windows Vista SP2 includes support for new types of hardware and emerging standards that will grow in importance in coming months, along with fixes discovered via automated error reporting as part of our Customer Experience Improvement program.

What makes the Windows Vista SP2 release unique is that it represents a single service pack which applies to both client (Windows Vista SP1) and server (Windows Server 2008) operating systems—since the code base for Windows Vista is shared with that for Windows Server® 2008, a single update can be deployed across your infrastructure. This service model also provides the ability to detect an incompatible driver and block service pack installation, or warn users of any loss of functionality during installation. Other highlights for IT pros include:

Emerging Hardware Support

• Bluetooth 2.1 feature pack
• Ability to record data on Blu-ray media
• exFAT file system now supports UTC timestamps, which enables correct file synchronization across time zones
• Support for the new VIA 64-bit CPU
• Support for ICCD/CCID smart cards

Hyper-V

• Provides the Hyper-V virtualization environment as a fully integrated feature of Windows Server 2008, including one free daughter OS with Windows Server 2008 Standard, four free licenses with Windows Server 2008 Enterprise and an unlimited number of free licenses with Windows Server 2008 Datacenter.

Security

• Windows Vista SP2 incorporates previously released reliability updates, as well as addressing crashes discovered since the launch of Windows Vista SP1

Performance

• Inclusion of Windows Search 4 for improved indexing performance, improved relevancy in search, broader indexing scenario inclusion, as well as new Group Policy integration for Windows Search
• Reduction of resources required for sidebar gadgets

Wireless

• Windows Vista Feature Pack for Wireless
• Fixed issue where Wi-Fi connection was no longer available after resume from sleep

Administration and Support Improvements

• Service pack clean-up tool: Restores hard disk space by permanently deleting the previous versions of the files (Windows Vista RTM and Windows Vista SP1) that are being serviced by Windows Vista SP2

We encourage you to download this service pack and test it on your lab machines. You should find that most if not all of your applications continue to function properly with this release. Also, we should point out that either Windows Vista SP1 or Windows Server 2008 is a prerequisite for installing this service pack.
