Microsoft releases the first so called Feature Pack for Windows Vista.
The Windows Vista Feature Pack for Wireless enhances the Vista Bluetooth support with version 2.1 support, unified pairing user interface and Windows Connect Now updates.
Microsoft notes that you need new hardware to utilize these new features. The Knowledge base entry describes all files, but does not offer download link. Possibly the Feature Pack is only for OEMs.
