How to Replace Microsoft Bluetooth Stack

Bluetooth connects devices wirelessly.

The term "Bluetooth stack" refers to the software that supports Bluetooth technology on a PC. Bluetooth is a low-power wireless technology for connecting devices such as digital cameras, cell phones, headsets, microphones and GPS to each other or to a computer with a Bluetooth adapter. Bluetooth devices work best within a range of approximately 30 feet, although greater ranges are possible. Windows XP Service Pack 2 installs a generic, signed Microsoft device driver that prevents third-party drivers from loading unless it's disabled.

Instructions

1. Press the "Windows" and "R" keys at the same time to open the "Run" window. Type "sysdm.cpl" in the "Open" box and click "OK."

2. Click the "Hardware" tab and then "Device Manager." Click the "+" sign next to "Bluetooth Radios" to expand it.

3. Right-click each device listed under "Bluetooth Radios," select "Uninstall" and then click "OK." Close "Device Manager" and click "OK."

4. Press the "Windows" and "R" keys at the same time, type "%windir%\inf" in the "Open" box and click "OK."

5. Right-click "bth.inf" and choose "Rename." Rename "bth.inf" to "bth.inf.old" and press "Enter." Right-click "bth.pnf" and "Rename" it to "bth.pnf.old." Restart your computer. The Microsoft Bluetooth stack will no longer load.

6. Install the Bluetooth driver that ships with your device.
