* The [[Windows Vista]] Bluetooth stack is improved with support for more hardware IDs, EDR performance improvements, ''Adaptive frequency hopping'' for Wi-Fi co-existence, and ''Synchronous Connection Oriented'' (SCO) protocol support which is needed for audio profiles.<ref name="MSBTFAQ"/> The Windows Vista Bluetooth stack supports a kernel mode [[device driver|device driver interface]] besides the user-mode programming interface, which enables third-parties to add support for additional Bluetooth Profiles such as SCO, SDP, and L2CAP. This was lacking in the Windows XP Service Pack 2 built-in Bluetooth stack, which had to be entirely replaced by a third-party stack for additional profile support. It also provides RFCOMM support using sockets besides virtual COM ports.<ref>{{cite web|url=http://download.microsoft.com/download/9/8/f/98f3fe47-dfc3-4e74-92a3-088782200fe7/TWMO05002_WinHEC05.ppt |title=USB/1394 on the PC |date= |accessdate=2012-11-04}}</ref> KB942567 called Windows Vista Feature Pack for Wireless adds Bluetooth 2.1+EDR support and remote wake from S3 or S4 support for self-powered Bluetooth modules.<ref name="MSBTFAQ"/> This feature pack while initially only available to OEMs, was eventually included in Windows Vista Service Pack 2.
