As we’ve previously reported, the service pack will be available via Microsoft’s Windows Update mechanism
If you haven’t yet heard, the update brings native support for Blu-ray burning and Bluetooth 2.1, improvements to Windows Search and Wi-Fi configuration. In a typical fashion, it will include all of the updates and security fixes released since the previous service pack, and will require SP1 to be installed.
The company warns that if you have used “vLite” to customize your Vista installation, it may have deleted required system components which could prevent SP2 from installing. They have, however, provided a workaround.
