Which previous versions of Windows support Bluetooth wireless technology?
The following previous versions of Windows include in-box support for Bluetooth wireless technology:
All SKUs of Windows 8.1All SKUs of Windows 8All SKUs of Windows 7All SKUs of Windows VistaAll SKUs of Windows XP with Service Pack 2 (SP2) and later
The following previous versions of Windows do not have in-box support for Bluetooth wireless technology:
All SKUs of Windows Server 2012All SKUs of Windows Server 2008 R2All SKUs of Windows Server 2008All SKUs of Windows Server 2003All SKUs of Windows 2000Although these versions of Windows do not have in-box Bluetooth wireless technology support, third-party Bluetooth drivers might be available from independent hardware vendors (IHVs).
Which Bluetooth versions do previous versions of Windows support?
Windows supports Bluetooth version 1.1 and later versions. Note that Bluetooth version 2.1 radios and devices are backward compatible with earlier versions of Bluetooth and will run on Windows XP and Windows Vista without SP2. However, these Windows versions cannot take advantage of the full Bluetooth version 2.1 feature set because the Bluetooth version 2.1 specification was not ratified before Windows Vista was released.
Windows 8 is Bluetooth Smart Ready, it supports Bluetooth version 4.0, and is able to connect with Bluetooth Smart devices.
Windows support for different versions of the Bluetooth specification depends on the Windows version, as shown in the following table:

* EDR support starting in Windows Vista and later is enhanced relative to the Bluetooth stack for Windows XP.
** Windows Vista with SP1 supports Bluetooth version 2.1 if it includes a package that was made available only to system partners. Windows Vista with SP2 integrated the Bluetooth version 2.1 support into the service pack release so that it is available to all customers.

Which Bluetooth profiles have in-box support in previous versions of Windows?
Windows 8.1 and Windows 8 In-Box Bluetooth Profiles
Because Windows 8.1, Windows 8, Windows 7, and Windows Vista provide both kernel-mode and user-mode programming interfaces for their Bluetooth stacks, hardware and software vendors can implement additional profiles in both kernel mode and user mode. We encourage vendors that create such profiles to test their software by using the appropriate Windows Hardware Certification Kit (HCK) test suites and have their software packages digitally signed
Windows 7 and Windows Vista In-Box Bluetooth Profiles
Windows 7 and Windows Vista include additional and updated Bluetooth profiles as listed in the following table:
Windows included in-box support for the following Bluetooth profiles:

Do users have to re-pair their Bluetooth devices after they upgrade a system to Windows 8.1?
If users upgrade from Windows 7 to Windows 8.1, they must perform a clean installation of Windows 8.1. In this situation, any Bluetooth software that the OEM provides must be re-installed and all devices must be re-paired. If users upgrade from Windows 8 to Windows 8.1, complex devices such as phones might require re pairing so that third-party drivers will reload. However, a simpler device such as a keyboard or a mouse does not require re-pairing.
Therefore, pairing information is preserved if users upgrade from Windows 8 to Windows 8.1 for some devices, primarily Bluetooth keyboards, mice, and audio devices. This ensures that customers are not required to use a wired keyboard and mouse to upgrade their Windows version. They can use their Bluetooth keyboard and mouse for the entire procedure.
What programming interfaces were introduced in Windows 8.1?
Windows 8.1 introduces new Windows Runtime APIs for accessing the RFCOMM (over standard Bluetooth) and GATT (over Bluetooth Low Energy).
What programming interfaces were introduced in Windows 8?
Windows 8 introduces new APIs for accessing Bluetooth Smart peripherals via Bluetooth Low Energy, creating a bus driver for non-USB Bluetooth controllers via an extensible transport model, and creating enhanced L2CAP channels. For more information about these APIs, see Bluetooth Devices Reference.
What programming interfaces were introduced in Windows 7?
Windows 7 introduced new Ex versions of previous APIs to provide enhanced functionality. For example, the BluetoothAuthenticateDeviceEx function lets out-of-band data be passed into the function call for the device that is being authenticated. Similarly, the BluetoothRegisterForAuthenticationEx function includes pin request and numeric comparison functionality. Also, the BluetoothSendAuthenticationResponseEx function is called when an authentication request to send the numeric comparison response is received. For more information about the new Ex versions of these APIs, see Bluetooth Functions.
What programming interfaces were introduced in Windows Vista?
Windows Vista introduced a kernel-mode DDI for Bluetooth wireless technology, which provides access to SCO, SDP, and L2CAP. The DDI is included with Windows Driver Kit (WDK) build 6000, which was released with Windows Vista, and all later builds of the WDK. We do not intend to make the kernel-mode DDI available on earlier versions of Windows. The Windows Hardware Certification Kit (HCK) can be used to verify that kernel-mode Bluetooth drivers comply with standard driver development practices and use the DDI correctly.

Windows Vista with SP2 and Windows 7 also support the user-mode RFComm and Bluetooth APIs. For more information, see the Bluetooth design guide. The WDK includes documentation for the new kernel-mode DDI. For more information about how to download the WDK, see Other WDK downloads The HCK includes documentation for Driver Test Manager (DTM). For more information about how to download the HCK, see the Windows Hardware Certification Kit (HCK) documentation.
